We describe the preparation of alkylsubst. benzodioxoles, -dioxane, -dioxepine and dioxocine 2a-e.
The can be subjected to a Vilsmeyer-formylation, yielding the aldehydes 3 a-e.
Treatment of 3 a-e with performic acid leads to the phenoles 4 a-e in a Baeyer-Villiger-Oxidation. Using Zincchloride as a catalyst the chromanes 5 a-j can be obtained by reaction of 4 a-e with either prenylbromide or phthylbromide.
