title: Brønsted acid-mediated stereoselective cascade construction of functionalized tetrahydropyrans from 2-(arylmethylene)cyclopropylcarbinols and aldehydes.
abstract: (E)- and (Z)-2-(Arylmethylene)cyclopropylcarbinols 1 could be converted to the corresponding tetrahydropyrans 2 and 3 stereoselectively in the presence of Brønsted acids MsOH or TsOH under mild conditions. A plausible Prins-type reaction mechanism has been proposed.
