Abstract

Abstract Novel optically active substituted acetylenes HC [TRIPLE BOND] CCH 2 CR 1 (CO 2 CH 3) NHR 2 [(S)-/(R)-1: R 1= H, R 2= Boc,(S)-2: R 1= CH 3, R 2= Boc,(S)-3: R 1= H, R 2= Fmoc,(S)-4: R 1= CH 3, R 2= Fmoc (Boc= tert-butoxycarbonyl, Fmoc= 9- fluorenylmethoxycarbonyl)] were synthesized from α-propargylglycine and α- propargylalanine, and polymerized with a rhodium catalyst to provide the polymers with ...
