对标题化合物(I)的△~(9(11))—双键硼氢化—氧化反应进行的研究表明:反应产物中除1la—羟基主产物(D)外,还有11β—羟基—9a—氢化合物(B)以及9a—羟基化合物(C)。在回收的未反应原料中分离出△~(9(11))—双键饱和化合物(A)。 化合物(I)与硼烷在四氢呋喃中密闭反应,过氧化
The study on the △ ~ (9 (11)) - double bond hydroboration-oxidation of the title compound (I) showed that in addition to the 1α-hydroxy primary product (D) Hydrogen compound (B) and 9a-hydroxy compound (C). A ~ (9 (11)) - double bond saturated compound (A) was isolated from the recovered unreacted starting material. Compound (I) and borane in tetrahydrofuran closed reaction, peroxidation
