Orsellinaldehyde is a dihydroxybenzaldehyde with a methyl side group. It can be classified as a resorcinol, benzaldehyde or toluene derivative. It is a natural product of several fungi. Fungi that contain it include Grifola frondosa,^[1] Aspergillus cleistominutus,^[2] Aspergillus nidulans,^[3] and Agrocybe praecox.^[4]

Production[edit]

Orsellinaldehyde can be produced by a Gattermann reaction of orcinol, using zinc cyanide under a hydrogen chloride atmosphere, which adds an aldimine (-CH=NH) group to the ring,^[5] followed by hydrolysis to give the aldehyde.^[5]^[6]

Properties[edit]

The melting point is between 181 and 183 °C.^[5]
