Abstract

Abstract: A number of cis-and trans-l, 2-disubstituted cyclopropanes have been synthesized in both racemic and optically active form. Their maximum rotations and absolute configurations have been determined by chemical correlation with trans-2- methylcyclopropanecarboxylic acid (6). Application of Brewster's rules of conformational asymmetry to the compounds prepared indicates that the theory is much more satisfactory ...
