Asymmetric dipolar cycloaddition reactions: a practical, convergent synthesis of chiral pyrrolidines
摘要:
Chiral trans-3,4-disubstituted pyrrolidines were obtained from the 1,3-dipolar cycloaddition of chiral alpha,beta-unsaturated N-acyloxazolidinones and azomethine ylide. (C) 1997 Elsevier Science Ltd.
