As exemplified by the transformation of allyl 2-nitrophenyl thioethers to 3,4-dihydro-2H-1,4-benzothiazines, the reductive cyclization of w-nitro alkenes to satd. N-heterocycles can be performed with high selectivity and high yields using a combination of MoO2Cl2(dmf)2 as a catalyst and Ph3P as reducing agent.
