Abstract
A TMSOTf‐catalyzed annulation was developed for the construction of polysubstituted maleimides from ynamides and alkynyl sulfoxides, using oxygen as a green oxidant and ynamides as both carbon and nitrogen sources. This novel protocol proceeds in the presence of TMSOTf without the need for an expensive catalytic system and tolerates a broad substrate scope, providing a variety of maleimides in generally moderate to good yields under mild reaction conditions.
期刊介绍：
Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC)
The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
