Embodiment 1
[0051] Example 1 Preparation of Chiral Dihydropyran Ring Derivatives
[0052] The specific preparation reaction is as follows:
[0053]
[0054] The hydroxy ketone (0.30 mmol) represented by formula 2, the chiral metal rhodium (0.009 mmol, metal catalyst), Molecular sieves (300mg) were dissolved in 3.0mL of organic solvent dichloromethane to configure mixed solution 1, and the diazo compound (0.6mmol) shown in formula 1 was dissolved in 3.0mL of organic solvent dichloromethane to configure solution 2; in- At 60°C, add solution 2 to the aforementioned mixed solution 1 with a syringe pump within 1 hour, and stir vigorously; after the dropwise addition of the mixed solution is completed, stir at -60°C for 5 to 8 hours until the diazo compound is completely consumed; Filtration, column chromatography separation and purification, to obtain the pure product, namely the target product.
[0055] The structures of the prepared compounds 1 to 32 are shown in Table 1, and the speci...
