Intramolecular cyclisation of acyclic triene esters derived from dichloromaleic anhydride affords bicyclic lactones, which by dechlorodecarboxylation, dechlorination or dehydrochlorination are readily elaborated to give novel unsaturated lactones.

Diels-Alder reaction of dienyl ff-methacrylthioimidates has been investigated under thermal or Lewis acid or protonic acid catalyzed conditions. The utility of the reaction is shown by desulfurative ring contraction of bicycle L4.4.0 1 to bicycle [ 4.3.0 I system.
