Stereoselective 1,4-phenyl migration from silicon to carbon in a-siloxy cyclic acetal systems: a concise synthesis of 1,2-cis-phenyl C-glycoside and enantio-enriched silanol.
[摘要]:The treatment of O-glycoside with alc. in the presence of montmorillonite K10 clay and 4-?MS yields the 1,4-aryl migration product with a 1,2-cis-Ph C-glycoside scaffold and a chiral silyl moiety with high stereoselectivity.
