Stereoselective Synthesis of Fluoroalkylated Butanolides
摘要:
Starting from fluoroalkylated, optically active acyl oxazolidinones the corresponding di- and trisubstituted butanolides were prepared in enantiomerically pure form. Using a divergent synthetic route highly functionalized fluoroalkylated building blocks are accessible.

A novel conjugate hydrofluoroalkylation of α,β-unsaturated acyl-oxazolidinones is described. Using this method, enantiomerically pure β-trifluoromethylated amino acids were prepared. Trifluorovaline and trifluoroisoleucine were incorporated into peptides and found to show extremely low α-helix propensities.
