Process for the enantioselective production of α-vinyl-α-aminocarboxylic acids

α-Vinyl-α-aminocarboxylic acids of the general formula: STR1 where * indicates a center of asymmetry and R is hydrogen, deuterium, lower alkyl, allyl, benzyl, or benzyl substituted 1 to 3 times by alkyl, alkoxy, fluorine or chlorine and produced enantiose

Methionine as Precursor for the Enantioselective Synthesis of α-Branched Vinylglycines and of Other Amino Acids

Methionine is converted by previously published methods into the diastereoisomerically pure 3-thiabutyl-substituted oxazolidinone (7) and imidazolidinones 5 and 6.An X-ray crystal structure determination of cis-3-benzoyl-2-(tert-butyl)-4-(3-thiabutyl)oxaz
