Abstract

Abstract A novel stilbene-ether type of photolabile protecting group (PPG) for hydroxyl group has been developed. It contains a stable aryl ether group in the protected form and can be deprotected by acid-catalyzed photorearrangement under 300-nm irradiation. The selective deprotection has also been achieved by irradiation of the mixture of 4-alkoxystilbene and 2- (4-alkoxystyryl) furan at 365 nm.
