    Abstract
    A formal, one-pot, [4+4] cyclization pathway for the generation of 8-member sultams via in-situ generation of an ortho-quinone methide (o-QM) is reported. The pairing of ambiphilic synthons in a complementary fashion is examined whereby o-fluorobenzenesulfonamides are merged with in-situ-generated o-QM in a formal [4+4] cyclization pathway to afford 5,2,1-dibenzooxathiazocine-2,2-dioxide scaffolds under microwave (mW) conditions. The method reported represents the first use of an o-QM in a formal hetero [4+4] cyclization.
