873397-34-3, Tetrahydro-2H-pyran-3-carboxylic acid is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Thionyl chloride (0.17 mL, 2.4 mmol) was added to a stirred solution of tetrahydro-pyran-3- carboxylic acid (0.26 g, 2.0 mmol) in DCM (4 mL) and DMF (0.1 mL). The mixture was stirred at room temperature for 30 min then Meldrum’s acid (0.576 g, 4.0 mmol) was added and the mixture was left to stir at room temperature for 1 hour. The reaction mixture was washed with a 2 N HC1 (aq) solution and evaporated under reduced pressure. The residue was dissolved in methanol and heated to reflux for 6 h. The mixture was then concentrated under reduced pressure to give the title compound (0.27 g, 75percent yield) which was used in the next step without further purification.
