One-Pot Cycloisomerization/Hetero-Diels–Alder Reaction of 1,6-Enynes with Aldehydes Catalyzed by Rhodium and a Brønsted Acid
摘要:
A rhodium and Bronsted acid catalyzed one-pot cycloisomerization/hetero-Diels-Alder reaction of 1,6-enynes with unactivated aldehydes was established under mild conditions. This one-pot catalytic protocol produced a wide variety of annulated dihydropyrans from readily available starting materials in a highly atom economical manner.
