Abstract

Memory of chirality in electrochemical carbon-carbon bond cleavage of N-o-phenylbenzoylated (S)-prolinol derivatives was observed. Substituents of the α-position affected the ee of the products. The reaction of α,α-diarylated (S)-prolinol derivatives proceeded smoothly to afford optically active α-methoxylated pyrrolidine with up to 73% ee.
