On ultraviolet irradiation O-acetyljervine (1) is subjected to several parallel fragmentations. From the complex reaction mixtures obtained in a variety of solvents (dioxan, tetrahydrofuran, acetonitrile, iso-octane, benzene) the major alicyclic products 6–8 and the heterocyclic compounds 12–16 have been isolated. Products 6–8 undergo further photochemical changes, e.g., decarbonylation of 7 to 9 and
在紫外线辐照下,O-乙酰胆碱(1)经历数次平行断裂。从在各种溶剂(二恶烷,四氢呋喃,乙腈,异辛烷,苯)中主要的脂环族产物的所得复合反应混合物6 - 8和该杂环化合物12 - 16已被分离。产品6 - 8经历进一步的光化学变化,例如,脱羰7至9和的水解分裂8至10。
