Steroidal alkaloid pdf

Spirosolanes: Compounds such as tomatidine and solasodine have the basic nitrogen included into an oxaazaspirane unit that includes the original steroidal side chain. Solanidine alkaloids: Solanidine biosynthesis involves the intermediates verazine and etioline. These alkaloids also are usually glycosides. 22,26-Epiminocholestanes: Alkaloids with this structure are intermediates in the biosynthesis of spirosolane, solanidine, a -epiminocyclohemiacetal, and 3-aminospirostane alkaloids. 3-Aminospirostane alkaloids: Alkaloids of this group, such as juribidine, are probably synthesized analogously to the corresponding spirostanols, ., tigogenin. The 3-amino group is probably introduced late in the biosynthesis by transamination.
