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).
