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.
