The new pyrrolo[3,4-b]quinolin-9-one system has been synthesized via m
etachloroperbenzoic acid oxidation of quinolones 5 and 10. These latte
r compounds were obtained by O-2 oxidation of 1,2,3,4-tetrahydro-beta-
carbolines. The unexpected m-CPBA oxidation has been studied in connec
tion with the Polonovski reaction. (C) 1997 Published by Elsevier Scie
