Rhodium-catalyzed synthesis of multi-substituted furans from N-sulfonyl-1,2,3-triazoles bearing a tethered carbonyl group†
Abstract
The efficient synthesis of highly functionalized furan derivatives from 1-sulfonyl-1,2,3-triazoles with a pendent carbonyl group is reported. The process involves an intramolecular trapping of α-imino carbene and subsequent aromatization.
