Due to the greater reactivity of triple bonds to several of the more common addition reactions, (i.e. reduction, 1 hydroboration,2 and acid-catalyzed hydration3) it is generally very difficult to selectively induce double bonds to undergo addition in the presence of triple bonds. We report

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
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,
