AN ALTERNATIVE ROUTE TO (+/-)-EMETINE AND (+/-)-DIHYDROCORYNANTHEINE

An alternatie synthesis of (+/-)-emetine(11) and (+/-)-dihydrocorynantheine(13) has been developed in formal sense starting from methyl 3-formylhexanoate(3).

Quinolizidines-V. A novel synthetic route to Ipecac alkaloids through chemical incorporation of ethyl cincholoiponate derived from the cinchona alkaloid cinchonine

A new synthetic route to (-)-emetine (1) and related Ipecac alkaloids has been exploited in terms of the synthesis of the tricyclic ester (-)-30 from ethyl cincholoiponate [(+)-4], a degradation product of the Cinchona alkaloid cinchonine (7). The steps i
