Autoxidative Annulation Cascade of the α-Cyano β-TMS-capped Alkynyl Cycloalkanone System
摘要:
The autoxidative annulation cascade promoted by an a.-cyano beta-TMS-capped alkynyl cycloalkanone system under catalysis with pyridine in one oxygen atmosphere has proven to be highly viable. On the basis of this newly developed protocol, a variety of highly functionalized bicyclic frameworks can be effectively constructed.

Under catalysis with ZnI2, an effective annulation process of Ï-silylacetylenic α-cyano ketones, leading to the formation of various bicyclic frameworks characterized with a TMS-containing methylenecyclopentane ring, has been developed.
