Thio-Claisen rearrangement (α-allylation of α,β-unsaturated thioamides giving α-allylated β,γ-unsaturated thioamides 4) followed by Cope rearrangement has provided a new method for the preparation of α,β,ε,ζ-unsaturated thioamides 9.A series of α-allylate
Addition of Methyl But-2-enedithioate to Cyclopentadiene. Cyclopentadiene as a Dienophile

Methyl but-2-enedithioate (1) acts as a heterodiene in undergoing cycloaddition to cyclopentadiene as dienophile, giving the bicyclic thiopyran (4).A possible alternative mode of cycloaddition to give the norbornenedithioester (6) followed by rearrangement to (4) is ruled out by a control experiment using (6) prepared by a different route.
