between homoallylalcohols and mercaptans with aldehydes. In the case of tetrahydropyran products, the stereochemistry of the product was found to be directly correlated with the geometry of the homoallylalcohols; whereas the cross-cyclization of aldehydes with trans-homoallyl alcohols generated (up-down-up) 2,3,4-trisubstituted tetrahydropyran products exclusively, the reaction of aldehydes with cis-homoallyl
