Abstract
Recently a novel series of 2-(2-thio-3-substituted-6-
ethylamino)-1,3,5-thidiazino imino-11-(piprazine-1-yl)
dibenzob,f1,4 oxazepines IXB(a-f) was successfully
synthesized by the isomerisation of 2-(2-substitutedimino-6-
ethylamino)-1,3,5-dithiozino imino 11-(piprazine-1-yl) dibenzo
b,f1,4 oxazepines VIIIB(a-f) by 5% aqueous sodium
bicarbonate in ethanol medium. The structures of all synthesized
compounds were justified on the basis of chemical
characteristics, elemental analysis and spectral studies
