Highly Stereoselective Ene Reaction of Aldimines with 2-(Alkylthio)allyl Silyl Ethers
摘要:
A stereoselective ene reaction of aldimines with 2-(alkylthio)allyl silyl ethers was developed. Under the influence of Lewis acids, N-acylimine or geminal biscarbamates reacted with a (Z)-2-(methylthio)allyl silyl ether to afford syn adducts in >94% selectivity.
