The diethylisopropylsilyl (DEIPS) group which is a new protective group for alcohols has been first characterized. DEIPS group can be distinguished from t-butyldimethylsilyl, triethylsilyl, tetrahydropyranyl groups and 2-deoxy glycoside with high selectivity in removing under mild acidic condition,
The use of the tris(trimethylsilyl)silyl (sisyl) group as a photolabile protecting group for primary and secondary alcohols was demonstrated. Sisyl ethers of a number of alcohols (yields 70-97%) were stable to many synthetic protocols, but could be deprotected using photolysis to give the starting a
