Abstract
Exclusive formation of either 2- or 4-trifluoromethyl(1H,5)arylodiazep ines (5,7)/(6,8) was observed in the condensation of 1,1,1-trifloro-3- (isobutoxymethylene)-2-propanones 2/3 with o-arylenediamines 4 under m icrowave irradiation conditions. Thermal reactions under the same temp erature and time produced no products. Orthoaminophenols 9 and o-amino thiophenol 12 with 2 and 3 under the same conditions produced the resp ective oxazepines 10,11 and thiazepines 13,14. The. synthetic equvalen t 1 gave similarly benzimidazoles 15, benzoxazoles 16 and benzthiazole s 17. (C) 1997 Elsevier Science Ltd.
