Abstract

Helical substituted polyacetylenes were investigated for inducing enantioselective crystallization of racemic N-(tert-butoxycarbonyl) alanine (BOC-alanine) enantiomers. For this purpose, helical substituted polyacetylenes [(R)-PSA and (S)-PSA)] were dissolved in supersaturated racemic BOC-alanine solutions. Upon cooling the solutions,(R)-PSA preferentially induced BOC-l-alanine to crystallize, while (S)-PSA facilitated the ...
