naphthalene, in THF, at 0 °C led, after hydrolysis, to the recovery of the free alcohols, amines and thiols in very good yields. At least a phenyl group was required in the silyl protecting group for the success of the reaction. Some polyfunctionalised starting materials have successfully been deprotected. The stereochemical outcome of the deprotection of a silylated chiral secondary alcohol has also been
甲硅烷基保护的醇,胺和硫醇与锂粉和催化量的萘在THF中在0°C下反应,水解后,导致非常好的收率回收游离的醇,胺和硫醇。为了成功地进行反应,在甲硅烷基保护基中至少需要一个苯基。一些多官能化的起始原料已成功脱保护。还研究了甲硅烷基化的手性仲醇脱保护的立体化学结果,未观察到外消旋作用。该方法已证明是酸催化的甲硅烷基化方法的良好替代方法,后者对某些甲硅烷基化叔醇的脱保护没有用。
