28244-94-2, 4-Methylphenyl 2,3,4,6-tetra-O-acetyl-1-thio-¦Â-D-glucopyranoside is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Compound 3: To a solution of 2 (32.6 g, 71.8 mmol) in 500 mL of dry MeOH was added catalytic amount of sodium methoxide (NaOMe) and stirred for 3 h at ambient temperature. The reaction was neutralized by adding Amberlite IR-120 and filtered, the resulting solution was concentrated to dryness to give 3 (20.3 g, 99%) as white solid, which was directly used for next reaction without further purification. 11 NMR (MeOD, 600 MHz) delta 7.46 (2H, d, J=7.8 Hz), 7.12 (2H, d, J=7.8 Hz), 4.50 (1H, d, J=9.6 Hz), 3.85 (1H, d, J=12.6, 1.8 Hz), 3.66 (1H, dd, J=12.0, 5.4 Hz), 3.36 (1H, t, J=9.0 Hz), 3.24-3.28 (2H, m), 3.17 (1H, t, J=9.0 Hz), 2.13 (3H, s). 13C NMR (MeOD, 150 MHz) delta 138.90, 133.66, 131.33, 130.67, 89.79, 82.16, 79.81, 73.82, 71.50, 63.03, 21.24. HRMS (ESI-TOF) for C13H18O5SNa+ [M+Na]+ calcd 309.0767. found 309.0772.
28244-94-2, The synthetic route of 28244-94-2 has been constantly updated, and we look forward to future research findings.
