A novel mesoporous catalyst, CuAl-SBA-15, with a hexagonally ordered porous structure prepared via a soft-templating approach in a highly acidic medium is used for tandem C-C and C-O bond formation between phenols and allylic alcohols to afford a variety of dihydrobenzopyrans in good yields. The catalyst is also found to be highly active for the synthesis of vitamin E and can be recycled several times without significant loss of its activity.
929. Chrom-3-en-6-ols. The action of pyridine on alk-2-enyl-benzoquinones

Allylbenzoquinones are converted by treatment with pyridine into quinols and chrom-3-en-6-ols. The tendency for the latter reaction to occur increases as the benzoquinone ring becomes more highly substituted.
