Abstract
A set of four stereoisomeric compounds were designed and synthesized as ligands of protein kinase C (PKC). The compounds were simplified analogs of the alotaketals, a class of natural products that were predicted to be ligands of PKC by computational screening. Bioassays revealed that the orientation of the alkyl side chain of the analogs was important for PKC binding and that the stereochemistry of the fused ring moiety influenced the PKC isozyme selectivity.

Abstract
We have developed a Rh(III)-catalyzed diastereoselective [2+1] annulation onto allylic alcohols initiated by alkenyl C-H activation of N-enoxyphthalimides to furnish substituted cyclopropyl-ketones. Notably, the traceless oxyphthalimide handle serves three functions: directing C-H activation, oxidation of Rh(III), and, collectively with the allylic alcohol, in directing cyclopropanation to control diastereoselectivity. Allylic alcohols are shown to be highly reactive olefin coupling partners leading to a directed diastereoselective cyclopropanation reaction, providing products not accessible by other routes.

Abstract
Hemoproteins have recently emerged as promising biocatalysts for promoting a variety of carbene transfer reactions including cyclopropanation and Y-H insertion (Y = N, S, Si, B). For these and synthetic carbene transfer catalysts alike, achieving high chemoselectivity toward cyclopropanation in olefin substrates bearing unprotected Y-H groups has proven remarkably challenging due to competition from the more facile carbene Y-H insertion reaction. In this report, we describe the development of a novel artificial metalloenzyme based on an engineered myoglobin incorporating a serine-ligated Co-porphyrin cofactor that is capable of offering high selectivity toward olefin cyclopropanation over N-H and Si-H insertion. Intramolecular competition experiments revealed a distinct and dramatically altered chemoselectivity of the Mb(H64V,V68A,H93S)[Co(ppIX)] variant in carbene transfer reactions compared to myoglobin-based variants containing the native histidine-ligated heme cofactor or other metal/proximal ligand substitutions. These studies highlight the functional plasticity of myoglobin as a "carbene transferase" and illustrate how modulation of the cofactor environment within this metalloprotein scaffold represents a valuable strategy for accessing carbene transfer reactivity not exhibited by naturally occurring hemoproteins or transition metal catalysts.

Abstract
Developing catalysts that produce each stereoisomer of a desired product selectively is a longstanding synthetic challenge. Biochemists have addressed this challenge by screening nature's diversity to discover enzymes that catalyze the formation of complementary stereoisomers. We show here that the same approach can be applied to a new-to-nature enzymatic reaction, alkene cyclopropanation via carbene transfer. By screening diverse native and engineered heme proteins, we identified globins and serine-ligated "P411" variants of cytochromes P450 with promiscuous activity for cyclopropanation of unactivated alkene substrates. We then enhanced their activities and stereoselectivities by directed evolution: just 1-3 rounds of site-saturation mutagenesis and screening generated enzymes that transform unactivated alkenes and electron-deficient alkenes into each of the four stereoisomeric cyclopropanes with up to 5,400 total turnovers and 98% enantiomeric excess. These fully genetically encoded biocatalysts function in whole Escherichia coli cells in mild, aqueous conditions and provide the first example of enantioselective, intermolecular iron-catalyzed cyclopropanation of unactivated alkenes.

Abstract
The selective functionalisation of C-H bonds is a powerful strategy for the construction of organic molecules and the Rh(II)-catalysed C-H insertion reaction is a particularly robust and useful tool for this purpose. This review discusses the insertion of Rh(II) carbenes into C-H bonds that are activated by α-oxygen substituents, focusing on the trends that have been observed in reactivity and selectivity, and the applications of this reaction to the total synthesis of complex natural products.

Abstract
Highly reactive metal carbenes, generated from simple ketones via diazo compounds, including diazo-amides and -phosphonates, using a recyclable reagent in-flow, are transient but versatile electrophiles for heteroatom alkylation reactions and for epoxide formation. The method produces no organic waste, with the only by-products being water, KI and nitrogen, without the attendant hazards of isolation of intermediate diazo compounds.

Abstract
Rhodium(II) azavinyl carbenes, conveniently generated from 1-sulfonyl-1,2,3-triazoles, undergo a facile, mild, and convergent formal 1,3-insertion into N-H and O-H bonds of primary and secondary amides, various alcohols, and carboxylic acids to afford a wide range of vicinally bisfunctionalized (Z)-olefins with perfect regio- and stereoselectivity. Utilizing the distinctive functionality installed through these reactions, a number of subsequent rearrangements and cyclizations expand the repertoire of valuable organic building blocks constructed by reactions of transition-metal carbene complexes, including α-allenyl ketones and amino-substituted heterocycles.

Abstract
The systematic optimization of the structure of a novel 2,4,5-trisubstituted imidazole-based cholecystokinin-2 (CCK(2)) receptor antagonist afforded analogues with nanomolar receptor affinity. These compounds were now comparable in their potency to the bicyclic heteroaromatic-based compounds 5 (JB93182) and 6 (JB95008), from which the initial examples were designed using a field-point based molecular modeling approach. They were also orally active as judged by their inhibition of pentagastrin stimulated acid secretion in conscious dogs, in contrast to the bicyclic heteroaromatic-based compounds, which were ineffective because of biliary elimination. Increasing the hydrophilicity through replacement of a particular methylene group with an ether oxygen, as in 3-{[5-(adamantan-1-yloxymethyl)-2-cyclohexyl-1H-imidazole-4-carbonyl]amino}benzoic acid (53), had little effect on the receptor affinity but significantly increased the oral potency. Comparison of the plasma pharmacokinetics and the inhibition of pentagastrin-stimulated acid output following bolus intraduodenal administration of both 53 and 6 indicated that 53 was well absorbed, had a longer half-life, and was not subject to the elimination pathways of the earlier series.

Abstract
The 1,3-dipolar cycloaddition of 2-diazopropane 1 to propargylic alcohols is regioselective and leads to 3H-pyrazoles 3 in good yield. The surprising formation of the tetrasubstitued pyrazolenine 4c from HC=CCH2OH and 1 can be explained via the 1,3-dipolar cycloadduct intermediate followed by a second cycloaddition of 1 to the C=C double bond and loss of dinitrogen. The photolysis of the antibacterial pyrazolenines 3 and 4 selectively gives α and β dimethylcyclopropenyl alcohols 5 and 6.

Abstract
The reaction of 2-(3-diazo-2-oxopropane-1-yl)-2-methyldithiolane 9a, 2-(4-diazo-3-oxobutane-2-yl)-2-methyldithiolane 9c, and 2-(3-diazo-2-oxopropane-1-yl)-2-methyl-1,3-dithiane 9b with Rh(2)(OAc)(4) gave three-carbon ring-expansion products dithiocan-2-en-1-ones 13a, 13c and dithionan-2-en-1-one 13b, respectively. 2-(5-Diazo-4-oxopentyl)-2-methyldithiolane 9e also gave the five-carbon ring-expansion products dithionan-3-en-1-one 13e and 5-methylenedithionane-1-one 13'e. On the other hand, reaction of 2-(4-diazo-3-oxobutyl)-2-methyldithiolane 9d in the presence of AcOH gave the four-carbon ring-expansion product 16d substituted by an acetoxyl group. In addition, the reaction of 2-(3-diazo-2-oxopropyl)-2-methyl-3-oxathiolane 9f in the absence of AcOH gave 4-oxa-7-thiocan-2-en-1-one 19 via a sulfonium ylide intermediate, whereas, in the presence of AcOH, an alternative regioisomer 20 was also formed competitively with 19 via an oxonium ylide intermediate.
