Abstract
Abstract Using the transformation of allyl 2-nitrophenyl thioethers to 3, 4-dihydro-2H-1, 4- benzothiazines as an example the reductive cyclization of ω-nitroalkenes to saturated N- heterocycles can be performed highly selective and with high yields if a combination of MoO 2 Cl 2 (dmf) 2 as a catalyst and Ph 3 P as reducing agent are employed.
