A Prins cascade process was developed for the synthesis of tetrahydro-3H-spiro[isobenzofuran-pyran] derivatives in good yields and selectivity by the condensation of 3-[2-(hydroxymethyl)phenyl]but-3-en-1-ols with aldehydes or ketones. The reaction proceeds smoothly in the presence of indium(III) trifluoromethanesulfonate (30 mol-%) in dichloroethane at 80 C. This is the first report on the synthesis of tetrahydro-3H-spiro[isobenzofuran- pyran] scaffolds through a Prins cascade reaction. Copyright
Efficient synthesis of polysubstituted isochromanones via a novel photochemical rearrangement

A novel and convenient approach to the synthesis of polysubstituted isochromanones is described. Irradiation of 2-formyl phenylalkeno-derivatives with UV light in benzene solution afforded the corresponding products in up to 98% yield. The possible reaction mechanism is proposed and further supported by the isotopic experiments.
