Studies in sigmatropic rearrangement: Rearrangement of 4-(4-alkylsubstituted aryloxybut-2-ynyloxy)benzopyran-2-ones

4-(4-o-Cresoxybut-2-ynyloxy)benzopyran-2-one (3a) and 4-(4-p-cresoxybut-2-ynyloxy)benzopyran-2-one (3b) give products 5 and 6 respectively both containing exocyclic double bond in addition to normal products, 4-aryloxymethylpyranobenzopyran-5(2H)-ones (4a and 4b).Other 4-(4-alkyl substituted aryloxybut-2-ynyloxy)benzopyran-2-ones (3c-f) furnish exclusively the 4-aryloxymethylpyranobenzopyran-5(2H)-ones.
