Regioselective opening of ring E of solasodine under various conditions afforded (25R)-22,26-epiminocholesta-5,22(N)-diene-3beta,16beta-diyl diacetate (previously known as 3,16-diacetyl pseudosolasodine B), C(31)H(47)NO(4), or (22S,25R)-16beta-hydroxy-22,26-epiminocholesta-5-en-3beta-yl acetate (a derivative of the naturally occurring alkaloid oblonginine), C(29)H(47)NO(3). In both cases, the reactions are carried out with retention of chirality at the C16, C20 and C25 stereogenic centers, which ...[more]
