摘要
从- ab -胆甾醇-8-烯或- ab -胆甾醇-8β，9α-二醇制备了几种带8或9位氧功能的- ab -胆甾醇衍生物。它们包括两种标题化合物，分别是乙酰胆甾醇3和钙化前体3的全合成所必需的。
Calciferol and its relatives. Part XV. The preparation of des-AB-cholest-8-ene-8-carbaldehyde {1?-[(1R)-1,5-dimethylhexyl]-3a?,6,7,7a?-tetrahydro-7a?-methylindane-4-carbaldehyde} and 9?-chloro-des-AB-cholestan-8-one {5?-chloro-1?-[(1R)-1,5-dimethylhexyl]-7a?-methyl-trans-perhydroindan-4-one}
Several des-AB-cholestane derivatives, carrying oxygen functions at position 8 or 9, or both, are prepared from des-AB-cholest-8-ene or from des-AB-cholestane-8β,9α-diol. They include the two title compounds, required for the total synthesis of tachysterol3 and precalciferol3, respectively.
