Tetrahydro-4-pyrone tau siv rau hauv cov organic sib txuas ua lub tsev thaiv rau cov txheej txheem tshuaj lom neeg ntau dua vim tias nws koom nrog ntau yam kev cuam tshuam cycloaddition. Tetrahydro-4H-pyran-4-ib yog siv hauv cov organic sib txuas ua lub tsev thaiv rau cov txheej txheem tshuaj ntau dua vim tias nws koom nrog ntau yam kev cuam tshuam cycloaddition. Tetrahydro-4H-pyran-4-ib yog ua haujlwm hauv kev npaj 4-methoxytetrahydropyran-4-yl tiv thaiv pab pawg, sib xyaw ua ke ntawm cov tetra sib thooj hloov cov methanes.

Cov methyl enol ether yog cov muaj txiaj ntsig tiv thaiv tus neeg sawv cev rau cawv, piv txwv li hauv nucleotide synthesis, nrog qhov zoo dua 3,4-Dihydro-2H-pyran. Tetrahydro-4H-pyran-4-ib kuj tseem ua haujlwm hauv kev kawm txog enantioselective alpha-aminoxylation ntawm ketones nrog nitrosobenzene thiab L-proline hauv cov kua ionic. Nws ua rau muaj kev sib xyaw ua ke hauv kev npaj dipeptides thiab spiroimidazolones. Tetrahydro-4H-pyran-4-ib tus kuj tau ua haujlwm hauv kev xav tshuaj rau kev sib xyaw ntawm Penicillins thiab hauv lub nplhaib ntawm vitamin D3.
