摘要

Abstract: A simple three-step synthesis of two essentially new classes of bicyclic heterocyclic compounds, the syn-and anri-l, 5-diazabicyclo [3.3. O] octadienediones, from@-keto esters via the pyrazolinone and halopyrazolinone is described. The syn compounds (-3, 6-diene-2, 8-diones) are usually strongly fluorescent; the anti derivatives (-3, 7-diene-2, 6-diones) are normally nonfluorescent and very phosphorescent. A short form name, 9, 10- ...
