Abstract

A new photoremovable protecting group for carboxylic acids is introduced. The protecting group 1-[2-(2-hydroxyalkyl) phenyl] ethanone, HAPE, is used to protect various carboxylic acids. When photolyzed, the protected compound releases the acid in 70-85% isolated yields. The synthesis and the results of photorelease of the protected acids are presented here.
