A Ring Fragmentation Approach to Medium-Sized Cyclic 2-Alkynones
摘要:
Bicyclic gamma-silyloxy-beta-hydroxy-alpha-diazoketones, in which the C beta-C gamma bond is the ring fusion bond, productively fragment when treated with tin(IV) chloride to provide medium-sized cyclic 2-alkynones. This method provides good to excellent yields of 10-, 11-, and 12-membered alkynone products.
