摘要

DCNB: p-dicyanobenzene tertiary alcohol or weakly nucleophilic phenol was employed, 3, 4- dihydro-2H-pyran was formed as a major byprod~ ct.~ The stereochemistry of the transacetalization is to be noted. When irradiation of an equimolar mixture of cis-or trans-6- methyltetrahydropyran-2-yl ether 4 and an alcohol was conducted
