Abstract

Reinvestigation of the structure of borrecapine and borreline through extensive spectroscopic analysis of their authentic samples led to the assignment of their absolute configurations. Newly acquired spectroscopic data determined that the previously assigned relative configuration for borrecapine was incorrect and that the claimed absolute configuration of borreline should be revised to its enantiomer.

Keywords: Borrecapine; Borreline; Borreria capitata; Monoterpene indole alkaloid; Rubiaceae; Structure Revision.
