A one-pot procedure was developed to prepare the derivatives of naphtho[2,3-a]indolizine-7,12-quinones (6a~6d, 8a~8c, 10a~10c) in moderate yields (31%~82%) by a 1, 3-dipolar cycloaddition reaction of pyridinium N-ylides (4a~4(1), isoquinolinium N-ylides (7a~7c) or quinolinium N-ylides (9a~9c) to 1,4-naphthoquinone, followed by an aromatization, in the presence of tetrakispyridine cobalt( H ) dichromate (TPCD).

Key words: PYRIDINE P, COBALT COMPLEX, NAPHTHOQUINONE, INDOLIZINE P, QUINOLINE P
