## Abstract Summary: A diastereomeric pair of novel __N__‐propargylphosphonamidates, HCCCH~2~NHP(O)(CH~3~)O‐L‐menthyl was synthesized by the successive condensations of methylphosphonic dichloride with L‐menthol and propargylamine. The (__R__)‐P‐isomer (1a) was isolated, and the absolute configur
Optically active cyclobutyl (Z)-a,b-dehydro-a-dipeptides have been efficiently synthesized through the coupling of conveniently protected glycine or (S)-phenylalanine residues with a (Z)-dehydro-a-amino acid derivative prepared, in turn, from (-)-verbenone as a chiral precursor. The alternative use
Catalyzed hydrolysis of p-nitrophenyl esters of N-protected L or D-phenylalanine by optically active hydroxamic acid or dipeptides in the presence of CTABr micelles showed high enantioselectivity (D/L=5.68 for L-ZLysZ(MHX)), demonstrating control of the direction of the enantioselectivity based on t
