In accordance with the present invention, it is provided a process for producing chromans, comprising reacting a phenol, a formaldehyde and an alcohol in the presence of a secondary amine and an acid, to generate an alkoxymethylphenol compound with the ortho position to the phenolic hydroxyl group being substituted with an alkoxymethyl group, and reacting the alkoxymethylphenol compound with an unsaturated compound having a carbon-carbon double bond. Among the alkoxymethylphenol compounds generated as the intermediate products during the aforementioned reaction, specific ones are novel compounds.
