摘要

Abstract The stereoselective synthesis of either (E)-or (Z)-silyl enol ether from the same acyclic α, β-unsaturated ketone is reported. Highly (Z)-selective conditions were the use of [Rh (cod) 2] BF 4/DPPE at room temperature with no solvent, whereas (E)-selective conditions were the use of [Rh (cod) 2] BF 4/P (1-Nap) 3 (1-Nap= 1-naphthyl) under refluxing dichloromethane.
