Notes:
The steroid alkaloid soladunalinidine [5α-tomatidan-3β-amine, (25S)-5α,22βN-spirosolan-3β-amine, 2], isolated from Solanum dunalianum, is synthesized from tomatidine (5α-tomatidan-3β-ol, 1) via 5α-tomatidan-3-one (4) and its oxime 5 which is reduced to 2 as well as to its ring-E-opened (22S) and (22R) dihydro products 6 and 9, the N(22,26)-chloro-N(3)-(2-hydroxy-benzylidene) derivatives 8 and 11 of which are recyclized to N(3)-(2-hydroxybenzylidene)soladunalinidine (3). The 5α-spirosolan-3-amines stereoisomeric at C-22 and C-25, 5α-solasodan-3α-amine (13) and -3β-amine (15), are obtained in an analogous sequence of reactions from soladulcidine (5α-solasodan-3β-ol, 12).
