624734-17-4, 3-Methoxydihydro-2H-pyran-4(3H)-one is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,624734-17-4
3-Methoxy-tetrahydro-pyran-4-one* (1 g, 7.68 mmol), commercially available (R)-(+)-l- phenylethylamine (0.99 ml, 7.68 mmol) and Raney-Nickel (200 mg) in 10 ml of dry ethanol were stirred under a hydrogen atmosphere (5 bar) for 15 days. The reaction mixture was diluted with 20 ml of methanol and 20 ml of tetrahydroiurane, stirred for 15 minutes, filtered on a celite pad and concentrated under vacuum. The crude product was loaded on a SCX cartridge (50g). The cartridge was washed with methanol and the desired product was eluted with a 7 M solution of ammonia in methanol. The basic organic phase was concentrated under vacuum and the crude product was purified by flash chromatography(dichloromethane/methanol= 98/2%) to obtain 710 mg (3.02 mmol) of the desired product as single stereoisomer (diastereoisomeric purity confirmed and relative cis stereochemistry assigned by NMR).GC/MS (method 3B) Rt = 35.04 min* Tetrahedron Letters, 2005 , 447 – 450
The synthetic route of 624734-17-4 has been constantly updated, and we look forward to future research findings.
