4295-99-2, 4-Cyanotetrahydro-4H-pyran is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of tetrahydro-2H-pyran-4-carbonitrile (2 g, 18.00 mmol) in tetrahydrofuran (10 mL) at 0 – 5 C was added slowly LHMDS (21.59 mL, 21.59 mmol). The mixture was stirred for 1.5 hrs at 0 C. lodomethane (3.37 mL, 54.0 mmol) was added slowly and stirring was continued for 30 min at ~0 C and then for ~2 hrs at room temperature. The mixture was cooled to 0 C and carefully diluted with IN aqueous hydrochloride solution (30 mL) and EtOAc (5 mL) and concentrated under reduced pressure. The residue was taken up in diethylether and the separated organic layer was washed with brine, dried over sodium sulfate, filtered off and concentrated under reduced pressure providing crude 4-methyltetrahydro-2H-pyran-4-carbonitrile (1.8 g) as an orange oil, which was directly used in the next reaction without further purification. LCMS (m/z): 126.1 [M+H]+; Retention time = 0.44 min.
4295-99-2, The synthetic route of 4295-99-2 has been constantly updated, and we look forward to future research findings.
