A new cyclohexenone annulation has been developed which involves the reaction of α-n-butylthiomethylene ketones with 1-lithio-1-methoxycyclopropane to afford α-n-butylthiomethylene spirocyclobutanones which, as their trimethylsilyl cyanohydrins, undergo thermal ring expansion.
已经开发出一种新的环己烯酮环化方法,该方法涉及α-正丁基硫亚甲基酮与1-硫代-1-甲氧基环丙烷的反应,得到α-正丁基硫亚甲基螺环丁酮,其作为三甲基甲硅烷基氰醇,经历热环膨胀。
