Facile access to α,β-dehydroalanine and α,β-dehydroamino butyric acid derivatives from DL-serines and threonines

ABSTRACT: Not only α,β-dehydroamino acids are important constituents for a number of bioactive peptides in nature, but also they are important building blocks for a variety of synthetic amino acids in organic synthesis. Methods to prepare dehydroamino aci

Biomimetic seleninates and selenonates

The synthesis of a variety of pyranose-, nucleoside-, (amino acid)-, and polyhydric-based seleninic and selenonic acids by DMDO oxidation of the corresponding selenoesters is reported, as well as some unusual coupling reactions of the seleninate and selenonate functionality with biological nucleophilic groups (sulfhydryl, indole, phenol, imidazole, carboxamide) that are found in proteins and enzyme active sites.

An efficient synthesis of dehydroamino acids and dehydropeptides from O-Cbz and O-Eoc derivatives of serine and threonine

A simple and efficient method for the synthesis of dehydroamino acids from serine and threonine is reported. Various O-Cbz and O-Eoc derivatives of serine and threonine are prepared using CbzCl and EocCl, respectively, and are subjected to an anti-selective elimination on treatment with K2CO3 in DMF at 65 °C to afford dehydroalanine and dehydroamino butyric acid derivatives, respectively, in excellent yields. The high stability of these carbonate derivatives of serine and threonine allows their use in normal peptide synthesis as protected serine and threonine residues. Peptides synthesized by incorporating O-Cbz or O-Eoc derivatives undergo ready elimination under the reported conditions, to give the corresponding dehydropeptides in excellent yields. The reaction conditions are mild enough not to cause the racemization of other stereogenic centers present in the peptide.

The synthesis and properties of Gla- and Phe-containing analogues of cyclic RGD pentapeptides

Cyclopentapeptides containing the Arg-Gly-Asp motif have been synthesised using solid-phase assembly of side-chain-protected linear precursors, followed by solution-phase cyclisation. The replacement of the Asp residue by γ-carboxyglutamic acid (Gla) is a novel feature which gives rise to an analogue which inhibits cell adhesion, yet its congeners do not show activity in binding assays with recombinant integrin receptors. NMR techniques support a β/γ-turn conformation in most of the analogues. The Royal Society of Chemistry 2000.
