K. Mogilaiah et al., Synthesis of 3,8-di (2-substituted-1,8-naphthyridin-3-yl) benzo [1,2-e : 4,5-e] bis [1,3,4] oxadiazine-5,10 [1H, 6H]-diones, I J HET CHE, 9(4), 2000, pp. 311-312
Interaction of 2-substituted-1,8-naphthyridine-3-carboxylic acid hydrazides
1 with chloranilic acid 2 in anhyd ethanol yields 3,8-di (2-substituted-1,
8-naphthyridin-3-yl) benzo [1,2-e: 4,5-e'] bis [1,3,4] oxadiazine-5,10 [1H,
6H]-diones 3. All the compounds have been characterized by spectral and mi
croanalytical data. The antibacterial activity of these compounds has also
been studied.
