Abstract

The structures previously assigned to (-)-romucosine and (+)-cathafiline, N-(methoxycarbonyl) aporphine alkaloids from Rollina mucosa (Annonaceae) and Cassytha filiformis (Lauraceae) respectively, have been confirmed by total syntheses of the racemic substances. The key step of the syntheses involved formation of ring C of the aporphines by a radical-initiated cyclisation.
