Taking advantage of facilely available α-chloroketones as C(sp3)-based electrophilic partners and oxidized alkyne equivalents, we here present a novel CpxRh(III)-catalyzed enantioselective C−H [4+2] annulation sulfoximines under mild redox-neutral conditions to access S-chiral 1,2-benzothiazines. It represents the first example such C(sp3)-electrophiles enabling functionalization.
