A series of 6,7-diphenyl-2,3,8,8a-tetrahydro-1H-indolizin-5-one analogues were synthesized and evaluated for cytotoxic activity against eight human cancer cell lines. Compounds 18, 21, 28, 29, 30 and 31 showed cytotoxic activity with GI50 value
A New Synthesis of Septicine, a Secophenanthroindolizine Alkaloid
Mangla, V. K.,Bhakuni, D. S.
, p. 748 - 749 (2007/10/02)
Septicine , an alkaloid isolated from Ficus septica and Tylophora asthmatica, has been synthesized using 2-(3',4'-dimethoxyphenacyl)pyrrolidine (6) and 3,4-dimethoxy-phenylacetyl chloride (11) as the essential intermediates.Condensation of 6 and 11 affords 2-(3',4'-dimethoxyphenacyl)-N-(3'',4''-dimethoxyphenylacetyl)pyrrolidine (12) which on treatment with potassium-t-butoxide furnishes 6,7-di-(3',4'-dimethoxyphenyl)-5-oxo-1,2,3,5,8,8a-hexahydroindolizine (13).LAH reduction of 13 affords septicine (1), identical (co-TLC, IR, PMR, m.m.p.) with a natural sample.
