A new catalytic deacylation of acetates and benzoates through transesterification with methanol was developed (see scheme). Reactions with various acid‐ and nucleophile‐sensitive functional groups proceeded efficiently in the presence of a catalytic amount of the tetranuclear zinc cluster. The present catalysis is applicable to less‐reactive tertiary acetates, the deacylation of which is difficult

the electronic properties of silylethers, thus enabling selective oxidation of benzylic and allylic silylethers, despite steric factors. A subsequent one-pot reduction accomplishes the formal deprotection to the corresponding benzylic and allylic alcohols. This catalytic system allows the direct oxidative desymmetrization of bis-benzylic and bis-allylic silylethers to access synthetically useful
