The synthesis of novel ortho-coumaric acid derivatives, with an amide group linked with an olefin moiety, which introduced photoinduced switching of the intramolecular hydrogen bonds is presented. An intramolecular OH · O=C hydrogen bond formed in a Z-phenol compound was switched to an intramolecular NH · O hydrogen bond in Z phenolate state via deprotonation. The pK a value of the Z-phenol derivative was lower than that of E-phenol, and a novel photocycle system involving protonation and deprotonation processes was achieved.
