Regioselective synthesis of 6-halomethyl-5,6-dihydro-4H-1,2-oxazines based on cyclizations of arylalkenyl-oximes
摘要:
6-lodo- and 6-bromomethyl-5,6-dihydro-4H-1,2-oxazines were prepared by condensation of dilithiated acetophenone-oximes with allylbromide and subsequent regioselective iodine- or NBS-mediated cyclization. (C) 2008 Elsevier Ltd. All rights reserved.
