Synthetic Route of 4442-79-9 ,Some common heterocyclic compound, 4442-79-9, molecular formula is C8H16O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Example 10 l-(2-Cyclohexyl-l-hydroxyethyl)-2-phenyl-2,5-dihydro-4H-pyrazolo[3,4-c]quinolin-4-onePart A To a mixture of cyclohexylmethanol (5,0 mL, 36 mmol) and dichloromethane (27 mL) at 0 0C was added triethyl amine (27 mL), dimethyl sulfoxide (27 mL), and sulfur trioxide pyridine (8.5 g, 54 mmol). The reaction was stirred 2 hours before diluting with ethyl acetate and saturated aqueous ammonium chloride. The layers were separated and the aqueous layer was extracted with additional ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, filtered, and concentrated to 12 g of cyclohexylacetaldehyde as a yellow oil.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,4442-79-9, its application will become more common.
