A Rh-catalyzed 1,2-sulfur migration/aza-Diels–Alder cascade initiated by aza-vinyl carbenoids from sulfur-tethered N-sulfonyl-1,2,3-triazoles†
Abstract
A novel Rh(II) catalyzed intramolecular 1,2-sulfur rearrangement/intermolecular aza-Diels–Alder cascade initiated by azavinyl carbenes has been developed, efficiently affording sulfur-containing tetrahydropyridine derivatives or α,β-unsaturated imines with a broad substrate scope.
