ASYMMETRIC SYNTHESIS OF N-SUBSTITUTED (R)-2-[(PYRROLIDIN-1-YL)METHYL]PYRROLIDINES
摘要:
The preparation of (R)-2[(pyrrolidin-1-yl)methyl] pyrrolidine and (R)-1-methyl-2-[(pyrrolidin-1-yl)methyl]pyrrolidine (both in 85% ee) is reported. The key step in the synthesis involves the sparteine-mediated asymmetric functionalization of N-Boc pyrrolidine and subsequent trapping with 1-pyrrolidine-carbonyl chloride.
