Abstract
A new access to the indolo[2,3-a]quinolizine ring system was devised u sing the thermal decarboxylative ring-opening of 3-carboxyl isoxazoles into alpha-cyano aldehydes. Thus, from acetal 8b the indolo[2,3-a]qui nolizine 5 was obtained in four steps via the beta-carboline 11 which on heating gave compound 5.
