Indoles XIII. Syntheses and Stereochemistry of 14H-Bisindolo[2,3-a][3,2-h]quinolizine and of Some Benz[a]indolo[3,2-h]quinolizines
摘要:
Starting from hexahydrobenz[a]indolo[3,2-h]quinolizine (1a-c) and hexahydrobisindolo[2,3-a][3,2-h]quinolizine (4)(2) we succeeded in generating their completely dehydrogenated derivatives. The structures were investigated by H-1- and C-13-nmr spectroscopy as well as by X-ray analysis.
