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 substituted with an alkoxymethyl group, and reacting the alkoxymethylphenol compound with an unsaturated compound having a carbon--carbon double bond.

The compounds of formula (I): STR1 [in which: R1 and R2 are the same or different and each represents hydrogen or C1 -C5 alkyl; R3 represents hydrogen, an acyl group, a (C1 -C6 alkoxy)carbonyl group or an aralkyloxycarbonyl group; R4 and R5 are the same or different and each represents hydrogen, C1 -C5 alkyl or C1 -C5 alkoxy, or R4 and R5 together represent a C1 14 C4 alkylenedioxy group; n is 1, 2 or 3; W represents the --CH2 --, >CO or >CH--OR6 group (in which R6 represents any one of the atoms or groups defined for R3 and may be the same as or different from R3); and Y and Z are the same or different and each represents oxygen or imino] and pharmaceutically acceptable salts thereof have various valuable therapeutic effects on the blood system and may be prepared by a process which includes reacting a corresponding halopropionic acid derivative with thiourea.
