6β-nitrocholest-4-ene and 4β-nitrocholest-6-ene gave a mixture of (E)-19-hydroxyiminocholest-4-en-6β-ol and (E)-19-hydroxyiminocholest-5-en-4β-ol; this mixture arose in both cases from a photochemical nitro-nitrosooxy rearrangement followed by the Barton reaction. The structures of the products were established by their synthesis.
6β-nitrocholest-4-ene 和 4β-nitrocholest-6-ene 的光解得到 (E)-19-hydroxyiminocholest-4-en-6β-ol 和 (E)-19-hydroxyiminocholest-5-en-的混合物4β-醇;在这两种情况下,这种混合物都来自光
化学硝基 - 亚硝基氧基重排,然后是巴顿反应。产物的结构是通过它们的合成确定的。
