Various 2-(3′-phenylthiopropyl)cycloalkanones were prepared from the corresponding cyclic ketones and subjected to S-alkylation by triethyloxonium tetrafluoroborate followed by potassium -butoxide treatment to give bicyclic epoxides with new five-membered carbocycles. A related cyclization to a six-membered ring was also observed.
由相应的环状酮制备各种2-(3'-苯硫基丙基)环烷酮,并通过四氟硼酸三乙基氧鎓进行S-烷基化,然后用丁醇钾处理,得到具有新的五元碳环的双环环氧化物。还观察到六元环的相关环化。
