Abstract

Deprotection Deprotection O 0345 1-[2-(2-Hydroxyalkyl)phenyl]ethanone: A New Photoremovable Protecting Group for Carboxylic Acids. -The synthesis of a novel photoremovable protecting group for carboxylic acids is described. When photolyzed the protected compounds (V) release the acids (IV) in 70-85% isolated yield. -(ATEMNKENG, W. N.; LOUISIANA, L. D. I.; YONG, P. K.; VOTTERO, B.; BANERJEE*, A.; Org.
