The novel enantiopure synthesis of protected proline-cysteine analogs by means of 1,3-dipolar cycloaddition of homochiral thiazolines and azomethine ylides is described. The important role of the oxidation state of the sulfur atom of the dipolarophil

Here we report the diastereopure synthesis of a novel protected lanthionine derivative substituted with a cyclohexane ring as well as the diastereopure synthesis of an α-methyllanthionine derivative. By starting from enantiopure α,β-cyclohexane-su

Enantiopure 2-thia-4-azabicyclo[3.1.0]hexanes, which can be considered constrained cysteines, have been obtained from l-cysteine by application of the “self-regeneration of chirality” concept. The ...

The reactivity of 2,3-dehydroproline and 2,3-dehydropipecolic acid methyl ester derivatives with S-nucleophiles in the thio-Michael addition reaction has been explored. The addition of triphenylmethanethiol and subsequent trityl cleavage led to the c

The behavior of homochiral 2,3-dihydrothiazoles, easily available from l-cysteine in Diels-Alder reaction with different dienes, "en route" to sterically constrained modified cystines, has been studied. The oxidation level of the sulfur atom of the h

Many studies dealing with modified nanoparticles are based on the assumption that organic molecules form single-layer structure on their surface. In this work, we suggest a novel approach to study the important phenomenon of supramolecular chirality

This review provides an overview of the literature concerning the stereoselective synthesis of a large group of modified cysteines. The different synthetic approaches are classified according to the bonds formed to build the cysteine backbone skeleto

The modified cysteine ligand, S-benzyl-α-methyl-l-cysteine (HL2), was prepared from l-cysteine hydrochloride methyl ester. The reaction of commercial S-benzyl-l-cysteine (HL1) or HL2 with the dimer, [{(η-CMe)RhCl}(μ-Cl)], gives rise to the cationi
