Orsellinaldehyde

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

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

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