Abstract
Amino sugars are important constituents of a number of biomacromolecules and products of microbial secondary metabolism, including antibiotics. For most of them, the amino group is located at the positions C1, C2 or C3 of the hexose or pentose ring. In biological systems, amino sugars are formed due to the catalytic activity of specific aminotransferases or amidotransferases by introducing an amino functionality derived from L-glutamate or L-glutamine to the keto forms of sugar phosphates or sugar nucleotides. The synthetic introduction of amino functionalities in a regio- and stereoselective manner onto sugar scaffolds represents a substantial challenge. Most of the modern methods of for the preparation of 1-, 2- and 3-amino sugars are those starting from "an active ester" of carbohydrate derivatives, glycals, alcohols, carbonyl compounds and amino acids. A substantial progress in the development of region- and stereoselective methods of amino sugar synthesis has been made in the recent years, due to the application of metal-based catalysts and tethered approaches. A comprehensive review on the current state of knowledge on biosynthesis and chemical synthesis of amino sugars is presented.

Abstract
Several natural and synthetic polypeptides possess important antimalarial activity. Shorter peptides with potent antimalarial activity have also been described, among them linear di-, tri-, tetra- and pentapeptides and their cyclic analogs. In an attempt to find dipeptides with antimalarial activities we show that linear and cyclic dipeptides, the latter known as diketopiperazines, still retain the fundamental core to preserve antimalarial activity. Thirteen linear dipeptides and ten diketopiperazines were investigated. Eight linear dipeptides showed IC(50) values between 2.78 and 7.07 μM, while eight diketopiperazines were also active with IC(50) values between 2.26 and 4.26 μM on Plasmodium berghei schizont cultures.

Abstract
A practically simple three-component Strecker reaction for the asymmetric synthesis of enantiopure α-arylglycines has been developed. Addition of a range of aryl-aldehydes to a solution of sodium cyanide and (S)-1-(4-methoxyphenyl)ethylamine affords highly crystalline (S,S)-α-aminonitriles that are easily obtained in diastereomerically pure form. Heating the resultant (S,S)-α-aminonitriles in 6 M aqueous HCl at reflux resulted in cleavage of their chiral auxiliary fragments and concomitant hydrolysis of their nitrile groups to afford enantiopure (S)-α-arylglycines. The enantiopurities of these (S)-α-arylglycines were determined via derivatization of their corresponding methyl esters with 2-formylphenylboronic acid and (S)-BINOL, followed by (1)H NMR spectroscopic analysis of the resultant mixtures of diastereomeric iminoboronate esters.

Abstract
A sweeping structural revision of the sarcodonin natural product family (published structures 1a-13a) is proposed after extensive studies aimed at their chemical synthesis. Key features of revised structure 1b include replacement of the N,N-dioxide moiety with an oxime, ring-opening of the central diketopiperazine, and transposition of the terphenyl wing from the 1β-2β position of 1a to the 2β-3β position of 1b. This structure revision arose from the serendipitous synthesis of a benzodioxane aminal (44) whose structure was unambiguously determined by X-ray crystallography and whose spectral properties bore considerable resemblance to the published data for the sarcodonins. A versatile new method for O-arylation of hydroxamic acids is also reported herein, as well as a manganese(III)-mediated α-oxidation of hydroxamic acids to aminals.

Abstract
The structure of the unusual anthelmintic pyrrolobenzoxazine terpenoid natural product CJ-12662 was established by X-ray crystallography and partial synthesis from 2-chloronitrobenzene. An unusual Meisenheimer-type rearrangement was used to provide the core pyrrolobenzoxazine heterocycle, and coupling of a tetracyclic pyrrolobenzoxazine lactone with the terpene alcohol was used to complete the synthesis of CJ-12662.

Abstract
A novel route for the synthesis of cyclic peptides constrained by an aliphatic bridge between two C(alpha)sites, using a triply orthogonal protecting group strategy, is described. The synthesis of the orthogonally protected bis-amino acid 1, via an enantioselective route utilizing the Schöllkopf and Evans methodologies, is first described. This is then incorporated into a short, alanine-rich peptide 13, using a novel triply orthogonal protecting group strategy to couple first one, then the other, amino acid moiety in such a way that an aliphatic bridge is formed between the i and i + 4 positions. Unexpectedly, the resulting constrained peptide does not adopt a helical conformation: instead, it is shown by CD at low temperature to adopt a left-handed type II beta-turn conformation in aqueous media and a right-handed type I beta-turn conformation in TFE.
