Partial Synthesis of the Steroid Alkaloids Teinemine, 22-Isoteinemine, Etioline, and 25-Isoetioline

The rare 16α-hydroxylated steroid alkaloids teinemine , 22-isoteinemine , etioline , and 25-isoetioline are synthesized from the abundant spirosolane alkaloids tomatid-5-en-3β-ol and solasodine , respectively.The crucial stages of these syntheses are the conversion of 1 or 15 into the N-protected (22S,25S)-, (22R,25S)-, and (22S,25R) -22,26-epimino-3β-hydroxycholest-5-en-16-ones 6, 7, and 18 as well as their reductions with sodium/2-propanol to the 16α-hydroxy compounds teinemine (8), 22-isoteinemine (10), and (22S,25R)-22,26-epiminocholest-5-ene-3β,16α-diol (19), respectively.By treatment with sodium methanolate the N-chloro derivatives 9 and 11 of 8 and 10 afford etioline (12).In an analogous manner, the N-chloro derivative 20 of 19 is converted into 25-isoetioline (21).
