Abstract
Organophosphorus compounds play a vital role as nucleic acids, nucleotide coenzymes, metabolic intermediates and are involved in many biochemical processes. They are part of DNA, RNA, ATP and a number of important biological elements of living organisms. Synthetic compounds of this class have found practical application as agrochemicals, pharmaceuticals, bioregulators, and othrs. In recent years, a large number of phosphorus compounds containing P-O, P-N, P-C bonds have been isolated from natural sources. Many of them have shown interesting biological properties and have become the objects of intensive scientific research. Most of these compounds contain asymmetric centers, the absolute configurations of which have a significant effect on the biological properties of the products of their transformations. This area of research on natural phosphorus compounds is still little-studied, that prompted us to analyze and discuss it in our review. Moreover natural organophosphorus compounds represent interesting models for the development of new biologically active compounds, and a number of promising drugs and agrochemicals have already been obtained on their basis. The review also discusses the history of the development of ideas about the role of organophosphorus compounds and stereochemistry in the origin of life on Earth, starting from the prebiotic period, that allows us in a new way to consider this most important problem of fundamental science.

Abstract
This review summarizes the main synthetic routes towards α-hydroxyphosphonates that are known as enzyme inhibitors, herbicides and antioxidants, moreover, a number of representatives express antibacterial or antifungal effect. Special attention is devoted to green chemical aspects. α-Hydroxyphosphonates are also versatile intermediates for other valuable derivatives. O-Alkylation and O-acylation are typical reactions to afford α-alkoxy-, or α-acyloxyphosphonates, respectively. The oxidation of hydroxyphosphonates leads to ketophosphonates. The hydroxy function at the α carbon atom of hydroxyphosphonates may be replaced by a halogen atom. α-Aminophosphonates formed in the nucleophilic substitution reaction of α-hydroxyphosphonates with primary or secondary amines are also potentially bioactive compounds. Another typical reaction is the base-catalyzed rearrangement of α-hydroxy-phosphonates to phosphates. Hydrolysis of the ester function of hydroxyphosphonates leads to the corresponding phosphonic acids.

Abstract
Phosphonic and phosphinic acids, especially α-heteroatom-substituted ones, possess unique structural and physical features which enable them to act as hydrotically stable analogs to biological phosphates in biological processes. They also act as mimetics in the transition state of the protease-induced hydrolysis of dipeptides. The first half of this review focuses on selected new synthetic methods developed by our research group for the stereoselective synthesis of α-heteroatom-substituted phosphonic and phosphinic acid derivatives, including modified nucleotide analogs and phosphinyl dipeptide isosteres. In the latter half, this review summarizes the utility of difluoromethylenephosphonic acids and phosphonic acid esters in the development of enzyme inhibitors against protein tyrosine phosphatases, sphingomyelinases, purine nucleoside phosphorylases and thrombin. The enzyme inhibitors developed were used as probes to elucidate signal transductions and the mechanisms of enzyme actions. The findings of the studies are briefly described.

Abstract
It has been more than 50 years since the first phospho-aldol reactions of dialkyl phosphites were reported. These efficient P-C bond-forming reactions have become the cornerstone of methods for the synthesis of α-hydroxyphosphonates and, by numerous available substitution reactions, the synthesis of other α- and γ-substituted phosphonates and phosphonic acids. Much of the interest in α- and γ-substituted phosphonates and phosphonic acids has been stimulated by reports of their biological activity, which is often dependent upon their absolute and relative stereochemistry. In this chapter, we review diastereoselective and enantioselective additions of dialkyl phosphites to aldehydes and ketones, otherwise called the phospho-aldol, Pudovik or Abramov reactions.

Abstract
Protein tyrosine phosphatases (PTPs) are important therapeutic targets for medicinal chemists and biochemists. General strategies for the development of inhibitors of these enzymes are needed. Several modular strategies which rely on phosphotyrosine mimics are known for PTP inhibitors. Previous strategies include phosphonomethylphenylalanine (Pmp) derivatives which act as competitive inhibitors. Pmp amino acid derivatives have been used to develop specific inhibitors by incorporation into sequences recognized by the PTP of interest. We report the synthesis of a new phosphonotyrosine analog, l-phosphonobromomethylphenylalanine (BrPmp), which acts as an inhibitor of PTPs. The BrPmp derivative was prepared as an Fmoc-protected amino acid which can be used in standard solid phase peptide synthesis (SPPS) methods. The synthesis of the protected amino acid derivative requires 11 steps from tyrosine with a 30% overall yield. Enzyme inhibition studies with the PTP CD45 demonstrate that BrPmp derivatives are irreversible inhibitors of the enzyme. A tripeptide which incorporated BrPmp had increased inhibitory potency against PTP relative to BrPmp alone, confirming that the incorporation of BrPmp into peptide sequences provides additional context to improve enzyme binding.

Abstract
Optically active aluminum(salalen) complex 2 was newly synthesized in a modular synthetic manner, and it was found to serve as an efficient catalyst for hydrophosphonylation of aldehydes and aldimines, giving the corresponding alpha-hydroxy and alpha-amino phosphonates with high enantioselectivity, respectively. The scope of the hydrophosphonylation was wide, and both aliphatic and aromatic aldehydes and aldimines were successfully used as substrates for the reaction. The potent catalysis of the complex is attributed to its unique structure: it adopts a distorted trigonal bipyramidal configuration which allows the salalen ligand to take a cis-beta-like structure wherein the chiral amino group is located close to the metal center.

Abstract
This paper covers recent publications from our laboratory on the synthesis of a variety of phosphonate and phosphinate derivatives. New methods for the enantioselective synthesis of alpha-hydroxyphosphonates were established by Lewis acid-mediated cleavage of homochiral 1,3-dioxaneacetals with P(OEt)(3) and chiral metal ligand-mediated hydrophosphonylation of aldehydes. Two diastereomers of HPmp derivatives were prepared by an application of these methods. The HPmp derivatives were convered to FPmp derivatives but with low diastereoselectivity. Hydrophosphonylation of alpha-aminoaldehydes afforded threo- and erythro-beta-amino-alpha-hydroxyphosphonates under chelation and nonchelation controlled conditions, respectively. The asymmetric dihydroxylation of alpha, beta-, and beta, gamma-unsaturated phosphonates with AD-mix-alpha and AD-mix-beta reagents gave alpha, beta- and beta, gamma-dihydroxyphosphonates with high enantioselectivity. The method was applied to the kinetic resolution of racemic alpha-oxygetated beta, gamma-unsaturated phosphonates. Treatment of allyloxymethylphosphonates with the base afforded alpha-hydroxyphosphonates via the [2,3]-Wittig reaction. Threo- and erythro-beta-amino-alpha-hydroxyphosphinates were obtained with high diastereoselectivity by phosphinylation of alpha-aminoaldehydes in the presence of (R)- and (S)-ALB, respectively. The phosphinylation of alpha-oxygenated aldehydes afforded the corresponding alpha, beta-dioxygenated phosphinates, but with low diastereoselectivity. Sphingomyelin analogues containing CF(2)PO(OH)(2) were synthesized starting from (S)- and (R)-Garner aldehyde for the purpose of obtaining potent sphyngomyelinase inhibitors. A useful method for the synthesis of alpha, alpha-difluorobenzylphosphonates was established based on the cross coupling reaction of an iodobenzene derivative with ZnCuBr(2)CF(2)PO(OEt)(2). The synthetic utility of ZnCuBr(2)CF(2)PO(OEt)(2) was examined to obtain alpha, alpha-difluoromethylenenphosphonates. The method was applied to a synthesis of PNP-inhibitory active compounds by combination of the purine base and alcohols containing difluoromethylenephosphonate. The methodology for the beta-selective N-glycosylation of 2,3-dideoxy glucoside was established by introducing phosphonothioates at the 3-position of glycosyl doners instead of phosphonate. Synthesis of new acylic nucleotide analogues designed based on the structural modification of ARS2267 is also described. Finally, kiral synthesis of some phosphonates was achieved using lipase through kinetic resolution.

Abstract
Protein tyrosine phosphatase 1B (PTP1B) negatively regulates insulin signaling in part by dephosphorylating key tyrosine residues within the regulatory domain of the beta-subunit of the insulin receptor (IR), thereby attenuating receptor tyrosine kinase activity. Inhibition of PTP1B is therefore anticipated to improve insulin resistance and has recently become the focus of discovery efforts aimed at identifying new drugs to treat type II diabetes. We previously reported that the tripeptide Ac-Asp-Tyr(SO(3)H)-Nle-NH(2) is a surprisingly effective inhibitor of PTP1B (K(i) = 5 microM). With the goal of improving the stability and potency of this lead, as well as attenuating its peptidic character, an analogue program was undertaken. Specific elements of the initial phase of this program included replacement of the N- and C-termini with non-amino acid components, modification of the tyrosine subunit, and replacement of the tyrosine sulfate with other potential phosphate mimics. The most potent analogue arising from this effort was triacid 71, which inhibits PTP1B competitively with a K(i) = 0.22 microM without inhibiting SHP-2 or LAR at concentrations up to 100 microM. Overall, the inhibitors generated in this work showed little or no enhancement of insulin signaling in cellular assays. However, potential prodrug triester 70 did induce enhancements in 2-deoxyglucose uptake into two different cell lines with concomitant augmentation of the tyrosine phosphorylation levels of insulin-signaling molecules. Key elements of the overall SAR reported herein include confirmation of the effectiveness and remarkable PTP1B-specificity of the novel tyrosine phosphate bioisostere, O-carboxymethyl salicylic acid; demonstration that the tyrosine skeleton is optimal relative to closely related structures; replacement of the p-1 aspartic acid with phenylalanine with little effect on activity; and demonstration that inhibitory activity can be maintained in the absence of an N-terminal carboxylic acid. An X-ray cocrystal structure of an analogue bearing a neutral N-terminus (69) bound to PTP1B is reported that confirms a mode of binding similar to that of peptidic substrates.

Abstract
To improve the in vitro and in vivo potency of our first low molecular weight GPIIb/IIIa antagonist 1 (TAK-029), a series of 2-[4-[2-(4-amidinobenzoylamino)-2-(substituted)acetyl]-3-(2-methoxy-2-oxoethyl)-2-oxopiper-azinyllacetic acids were synthesized through modification of the glycine moiety of 1 and evaluated for their ability to inhibit in vitro adenosine 5'-diphosphate (ADP)-induced platelet aggregation of guinea pig platelet rich plasma (PRP). Among the compounds examined, the (3S,2S)-4-methoxyphenylalanine derivative 4h showed the most potent antagonistic activity with an IC50 value of 13 nM. Dose-dependent inhibition of ex vivo platelet aggregation was achieved with oral administration of 4h (0.3-1.0 mg/kg) to guinea pigs. Complete inhibition was observed for up to 8 h, and 43% inhibition could still be observed 24 h after oral administration of 1.0 mg/kg. The long-lasting antiplatelet effect of 4h suggests that 4h would be suitable for once-a-day dosing. Structure-activity relationships (SAR) were examined in the series of the phenylalanine derivatives. An increase in the electron density around the 4-position of the phenyl ring of the phenylalanine moiety led to an increase in the antiplatelet activity, suggesting the existence of a hydrophobic and electrostatic interaction site in addition to the ionic binding sites in the GPIIb/IIIa.
