摘要

Enantioselective deprotonation of symmetrical epoxides was studied by using chiral lithium amide, prepared from (S)-2-(N, N-disubstituted aminomethyl) pyrrolidine and butyllithium. Chiral allylic alcohols were obtained with moderate to high enantiomeric excesses (ee's)(41– 92% ee) from several cyclic and acyclic epoxides employing lithium (S)-2-(1- pyrrolidinylmethyl) pyrrolidide in tetrahydrofuran (THF) in the presence of 1, 8- ...
