Stereospecific Synthesis of two 9,11,12,13,13a,14‐hexahydrodibenzo[ f,h ]pyrrolo‐[1,2‐ b ]isoquinolines. The stereospecific synthesis of (13a S )‐(+)‐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.
