SYNTHESIS OF 2-[(2-PHENYLDIMINO-6-SUBSTITUTEDAMINO)-1,3,5-DITHIAZINO] IMIN-11-(PIPRAZINE-1 YL) DIBENZO[B,F][1,4] OXAZEPINES
D. T. Tayade* and P. R. Kale
Recently in this laboratory convenient method for synthesis of 2-[(2-phenylimino-6-substitutedamino)-1,3,5-
dithiazino]imino-11-(piprazine-1-yl) dibenzo [b,f] [1,4] oxazepines [VIIIB(a-h)] was developed. The interactions
of 2-[substituted-2,4-dithiabiureto]-11-(piperazin-1-yl)dibenzo[b,f][1,4]oxazepines [VB(a-h)] with
phenylisocyanodichloride (VIIa) in 50% acetone-ethanol medium were carried out on water bath to synthesized
[VB(a1-a36)] respectively. The structures of synthesized compounds were justified on the basis of chemical
characteristics, elemental analysis and spectral studies.
Keywords: Phenylisothiocyanate, 2-[substituted-2,4-dithiabiureto]-11-(piperazin-1-yl) dibenzo[b,f][1,4]oxazepines and 50% acetone-ethanol.
