Abstract:
The title compound, C29H24N2O3, was synthesized via a four-component Debus-Radziszewski reaction, involving benzil, amine, aldehyde and ammonium acetate. The OH group of the vanillin substituent forms both an intra-molecular and an inter-molecular hydrogen bond, the latter generating [010] chains. The extended structure is consolidated by weak C-H⋯O and C-H⋯π inter-actions, generating a criss-cross motif.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
