4. Asymmetric Multicomponent Reactions:  Diastereoselective Synthesis of Substituted Pyrrolidines and Prolines

Author

K. Ghosh, Arun, Kulkarni, Sarang, Xu, Chun-Xiao, and E. Fanwick, Phillip

Abstract

A novel diastereoselective synthesis of substituted pyrrolidines has been developed. Asymmetric multicomponent reactions of optically active phenyldihydrofuran, N-tosyl imino ester, and silane reagents in a one-pot operation afforded highly substituted pyrrolidine derivatives diastereoselectively. The reaction is quite efficient and constructed up to three stereogenic centers in a single operation.

Abstract

TiCl(4)-promoted multicomponent reactions involving N-tosyl imino ester, cyclic enol ether, and silane reagents in a single one-pot operation provide functionalized alpha-amino acids with multiple stereogenic centers in good to excellent yields. Cis/trans selectivities with optically active substituted dihydrofurans have been investigated.
