<i>N</i>-(TRIMETHYLSILYLMETHYL)AMINOMETHYL ETHERS AS AZOMETHINE YLIDE SYNTHONS. A NEW AND CONVENIENT ACCESS TO PYRROLIDINE DERIVATIVES

Abstract

Abstract The title compounds, readily prepared from (trimethylsilylmethyl)amines, formaldehyde and an alcohol, react with electron deficient alkenes in the presence of iodosilane or silyl triflate in combination with cesium fluoride to give the corresponding pyrrolidine derivatives stereospecifically in excellent yield.
