General description

4-Benzylidene-2-phenyl-2-oxazolin-5-one (4-benzal-2-phenyl-5-oxazolone) is an azlactone. The absolute configuration of the geometric isomers of 4-benzylidene-2-phenyl-2-oxazolin-5-one have been determined by NMR spectroscopy. It undergoes two primary photochemical processes, geometric isomerization and hydrogen abstraction from solvent.
