Deprotection of Tetrahydropyranyl and Silyl Ethers Catalyzed by Organotin Phosphate Condensates
20 August 2002 (online)
A new method for deprotecting tetrahydropyranyl and silyl ethers has been established by using organotin phosphate condensates as a catalyst. The reaction proceeds selectively under mild conditions. The heterogenous reaction enables easy separation of the catalyst, which can be reused for further reactions without purification.
