✦ Synopsis

Intramolecular Diels-Alder reaction of selenoaldehydes which were generated from bis(trimethylsily1) selenide and dienals gave the corresponding bicyclic adducts.

The first examples of intramolecular Diels-Alder reactions on indoles indicate that this reaction may be employed for the direct preparation of highly functionalized dihydroindoles. The hybridization of the atoms in the tether plays a crucial role.

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.
