摘要

Reaction of 3-methyl-2, 4-diphenyloxazolium 5-oxide (1) with cyclopentadienequinone and anthracenequinone, respectively, gave 1: l adducts 2 and 3 in which the elements of carbon dioxide have been retained. The N-bridged lactone structures assigned to 2 and 3 are based on the spectral analyses and chemical decompositions. Conversions of 2 and 3 into the corresponding pyrrolines 4 and 5 and pyrroles 6 and 7 are described. Formation of a ...
