Stereospecific Synthesis of two 9,11,12,13,13a,14‐hexahydrodibenzo[f,h]pyrrolo‐[1,2‐b]isoquinolines.The stereospecific synthesis of (13aS)‐(+)‐2,3,6‐ and 3,4,6‐trimethoxy‐9,11,12,13,13a,14‐hexahydrodibenzo[f,h]pyrrolo[1,2‐b]isoquinoline is described. The 2,3,6‐trimethoxy‐compound proved to be the optical antipode of (−)‐antofine, isolated from Cynanchum vincetoxicum L. Pers.
