    • 6 p-methoxystyryl group with phenyl, 2-furyl, styryl). In all cases the structure corresponding to 35 was the major product in 60-70% yield. In one case (styryl) a minor diastereomer (5%) was detected in which all substituents were equatorially disposed on the tetrahydropyran ring with the exception of the benzyloxymethyl group (axially disposed).
