Isosolacapine, a minor steroidal alkaloid of Solanum pseudocapsicum, earlier assigned structure 3, possesses a novel 22β N stereochemistry in a 22,26-epiminocholestane skeleton.This alkaloid has now been isolated from Solanum capsicastrum and its structure confirmed by its conversion to solanogantamine (8), a 22αH solanidane derivative ex Solanum giganteum.The ring-juncture stereochemistry of the indolizidine moiety of 22β H solanidanes, in general, has been elucidated on 13C and 1H NMR spectral evidences.
