Cassytha alkaloids. I. New aporphine alkaloids from Cassytha filiformis L

Abstract

Cassythine, C19H19N05, the major phenolic alkaloid of Cassytha filiformis L., is a new aporphine. Its NO-dimethyl derivative has been identified as the known alkaloid (+)-ocoteine (11), and from spectroscopic data cassythine is considered to be (Ia). A new non-phenolic base, cassythidine, C19H17NO5, is considered to be(IV).
