✦ Synopsis

The Structure of bis‐indoline alkaloids of a novel type

The structure of folicangine 4, a bis‐indoline alkaloid from the leaves of Voacanga africana, is obtained by correlation with voafolidine 3a and isovoafolidine 3b. It requires an ether bridge between the two parts of the molecule, as in subsessiline (amataine 5a). Subsessiline‐lactone, from the leaves of Voacanga thouarsii has structure 5b proved by correlation with 5a. The CD. curves of double‐indole alkaloids of vobtusine type are given (Table 3).
