General description

2-Methoxytetrahydropyran is methoxy-substituted tetrahydropyran. α- and β-glycosidic C1-O1 bonds of the axial and equatorial forms of 2-methoxytetrahydropyran has been investigated by ab initio conformational study. Stereochemical properties of the glycosidic linkage of 2-methoxytetrahydropyran have been studied by the quantum-chemical PCILO method. It undergoes elimination reaction in the gas phase to yield 3, 4-dihydro-2H-pyran and methanol. Proton resonance spectra of 2-methoxytetrahydropyran has been analyzed.

An ab initio conformational study of the alpha- and beta-glycosidic C1-O1 bonds has been carried out on the axial and equatorial forms of 2-methoxytetrahydropyran (2-MTHP) at the HF/6-31G(d,p) and GVB-PP/6-31G(d,p) levels of calculation. Six conformers of 2-MTHP were fully optimized
