Lewis Acid-Catalyzed Synthesis of Polysubstituted Furans from Conjugated Ene-yne-ketones and 1,3,5-Triazinanes

摘要

An efficient and metal-free approach to the construction of diverse functionalized furan derivatives has been developed from ene-yne-ketones and 1,3,5-triazinanes. As an atom-economical and environment-friendly protocol, the new conditionsare suitable for selective C-N and C-O bond formation of a wide range of polysubstituted furans in one pot
