Benzoxadiazines: Part III - Synthesis of 2,5,6-Triaryl-4H-1,3,4-oxadiazines
Rao, V. Rajeshwar,Rao, T. V. Padmanabha
, p. 979 - 981 (2007/10/02)
Two new routes have been developed for the synthesis of 2,5,6-triaryl-4H-1,3,4-oxadiazines (IV).The first route involves condensation of benzoin (I) with various aromatic acid hydrazides (II) followed by cyclisation of the resulting schiffs bases (III) wi
