synthesized by reaction of appropriate triazinone with POCl3 and subsequent treating of 8-chloro derivative with sodium ethoxide in ethanol. Furo[3,2-b]pyrrole-5carboxylates were hydrolysed to form acids, which underwent one-pot decarboxylation with TFA and formylation of the in situ formed furo[3,2-b]pyrrole with triethyl orthoformate to give 5-carbaldehydes. Hydrazinolysis of bis-esters led to bis-carbohydrazides
