First Synthesis of Methyl syn 3-CF3-Isoserinate

Abstract
A [2+2] cycloaddition of the trifluoromethyl aldimines 5 with a ketene provided stereoselectively the CF3-substituted β-lactam 4 in a 50 % yield. Further steps of ring opening and deprotections led to the methyl syn-3-CF3-isoserinate which is a new fluoro analogue of the C-13 side-chain of taxoids.
