INTRAMOLECULAR CYCLOADDITIONS USING VINYL SULFIDE DIENOPHILES
Williams, D.R.,Gaston, R.D.
, p. 1485 - 1488 (1986)
The formation of hexahydrobenzo(b)thiophenes have been examined by a Diels-Alder route featuring a vinylic sulfide as the dienophilic component.Unique aspects of the observed stereoselectivity and further stereochemical transformations are presented.
