Popis:	The oxidation of trans-2,6-diethoxy-Δ 3-dihydropyran with perbenzoic acid gave a mixture of stereoisomeric epoxides, from which one individual isomer was isolated. The configuration and conformation of the epoxide obtained was established by PMR spectroscopy. 2,6-Diethoxy-3-hydroxy-4-dialkylaminotetrahydropyrans were obtained by the reaction of 2,6-diethoxy-3,4-epoxytetrahydropyran with dimethylamine and piperidine; the structural direction of the opening of the epoxide ring was studied by mass spectrometry.
