ASYMMETRIC-SYNTHESIS OF R-BETA-AMINO BUTANOIC ACID AND S-BETA-TYROSINE - HOMOCHIRAL LITHIUM AMIDE EQUIVALENTS FOR MICHAEL ADDITIONS TO ALPHA,BETA-UNSATURATED ESTERS

Abstract:
Michael addition of the lithium amide derived from R-N-(α-methylbenzyl)benzylamine to benzyl E-crotonate is highly stereoselective (95% d.e.) giving after debenzylation and crystallisation homochiral R-β-amino butanoic acid. A similar addition to methyl E-(p-benzyloxy)cinnamate is completely stereoselective giving after debenzylation and acid hydrolysis homochiral S-β-tyrosine as its HCl salt. © 1993.
