Abstract
Diastereomeric α,β,α′,β′-diepoxy ketones and the products of their condensation with acetone were synthesized by oxidation of cinnamoyloxiranes with alkaline hydrogen peroxide. It is shown that the acidic hydrolysis of 2-methyl-1,2,4,5-di-epoxy-3-pentanones leads to ketones of the tetrahydropyran and tetrahydrofuran series. The stereochemistry of the hydrolysis products was confirmed by chemical transformations and spectroscopy.
