An Improved Stereocontrolled Route to cis-Erythrinanes by Combined Intramolecular Strecker and Bruylants Reaction. — A new stereoselective access to
cis-erythrinanes (VIIa-c) involving intramolecular Strecker reaction of cyclohexanoylphenethylamines (IV) followed by intramolecular Bruylants reaction of the aminonitriles (VI) thus formed as the key steps is developed. Attempts to obtain the C-ring
homologue schelhammerane (VIId) by this route fail. — (REIMANN*, E.;
ETTMAYR, C.; Monatsh. Chem. 135 (2004) 9, 1143-1155; Inst. Pharm., Zent.
