, p. 2823 - 2824 (1988)
A new chiral masked ketene synthon, R-(+)-ethynyl p-tolylsulfoxide reacts with cyclopentadiene to give two separable diastereomers.Both were transformed very easily in (+)-(1R,4R) and (-)-(1S,4S) dehydronorcamphor.
Reactions de Diels-Alder du (R)S-ethynyl p-tolylsulfoxyde

, p. 695 - 698 (2007/10/02)
Diels-Alder reactions of (R)S-ethynyl p-tolylsulfoxide 1 with some representative dienes have been studied.Smooth reaction of 1 with butadiene, 2-methylbutadiene and 2,3-dimethylbutadiene affords new dienic chiral sulfoxides in high yield.Asymm
