Significance
Various azomethine ylides derived from amino acids (glycine, alanine, phenylalanine, and leucine) undergo 1,3-dipolar cycloaddition with chiral acrylates to yield highly substituted pyrrolidine derivatives in good yields and high enantioselectivities. Using this cycloaddition as a key step, racemic and enantioselective syntheses of a hepatitis C RNA-dependent RNA polymerase inhibitor are presented.
