During the title reaction, the lithium alkoxides formed as intermediates undergo an intramolecular addition to the neighboring CN group followed an S to 0 benzothiazole transfer and simultaneous extrustion of sulfur dioxide and ejection of 2(3H)-benzothiazolone anion.

A short and efficient synthesis for beta-acyl and beta-alkoxycarbonyl heterocyclic sulfones containing benzothiazol (BT) and phenyltetrazol (PT) heterocydic core is presented here. The method seems to be general and provides the desired C-nudeophiles in very good to excellent yields from readily available starting materials.
