Heterocycles. 2012 Dec 31;86(2):10.3987/COM-12-S(N)122. doi: 10.3987/COM-12-S(N)122.

Abstract

The synthesis of a library of bicyclic sultams incorporating the 1,5,2-dithiazepine 1,1-dioxide moiety is reported. Following scaffold synthesis via a one-pot sulfonylation/intramolecular thia-Michael protocol, several additional cyclization strategies have been realized enabling access to new bicyclic sultams.
