Related Products of 3637-61-4, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.3637-61-4, name is Cyclopentanemethanol, molecular formula is C6H12O, molecular weight is 100.16, as common compound, the synthetic route is as follows.
cyclopentane methanol (119a) (500 mg) was dissolved in pyridine (5 mL), under ice cooling, added TsCl (1.43 g), and the reaction was stirred at room temperature for 36 hours. After concentrating the solvent under reduced pressure, the residue ethyl acetate(50 mL) was added to the organic layer saturated aqueous sodium hydrogen carbonate solution (50 mL), washed with saturated brine (50 mL), and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reducedpressure, the residue was purified by silica gel flash column chromatography (developing solvent nhexane:ethyl acetate =50: 1) to obtain a colorless cyclopentylmethyl tosylate (120a) (864 mg, 68% yield) to give an oil.
Statistics shows that 3637-61-4 is playing an increasingly important role. we look forward to future research findings about Cyclopentanemethanol.
