Orientation in acylation reactions of 2,2-dimethyl-2H-chromenes was studied. Five acetylchromenes were obtained with two methods and six formylchromenes were obtained with a third method. Demethylation of four acyl-methoxy-substituted chromenes gave the corresponding acylchromenols. 2,2-Dimethyl-2H-chromene-6-carboxylic acid (anofinic acid) was also obtained by oxidation of 6-formylchromene.
The present invention provides a hair growth stimulant comprising a chromene compound as an active ingredient, and which exhibits excellent hair restoration effects. The present invention also provides a hair-restoring preparation for external use, hair-restoring preparation for oral use, and hair-restoring food containing the hair growth stimulant.
