Photodeprotection

WebThe photodeprotection at 254 nm was followed by 1 H NMR, indicating the release of phenylpropiolic acid, which further underwent copper-catalyzed decarboxylative cleavage in situ to yield a terminal alkyne, phenylacetylene. In addition, the benzylic position of the NB group was modified with methyl, vinyl, allyl, and phenyl moieties.
