摘要：

Furazan (1,2,5-oxadiazole) derivatives are obtained along with isoxazolines from the reaction of benzoylnitromethane with dipolarophiles in the presence of DABCO. Furazans are shown to derive from the intermediate dibenzoylfuroxan (3,4-dibenzoyl-1, 2,5-oxadiazole-5-oxide) and dipolarophiles under hydrolytic conditions. ((c) Wiley-VCH Verlag GmbH & Co.
