Photorelease Study of γ- Amino Glutamate from 1,2,2-triphenyl-ethanone

A phototrigger, 1,2,2-triphenylethanone (TPE), was synthesized for the photorelease study. The photorelease of 1,2,2-triphenylethanonyl N-t-Boc-γ-amino glutamate (TPE- N-t-Boc-GABA) showed the quantum efficiency of φ = 0.75. The phototrigger underwent further transformations that yielded Benzo[b]phenanthro[9,10-d]furan (9).
