Synthetic Route of 23783-42-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 23783-42-8, name is 2,5,8,11-Tetraoxatridecan-13-ol, molecular formula is C9H20O5, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
2,5,8,1 1-Tetraoxatridecan-13-ol (5.0 g, 24.01 mmol) was dissolved in THF(20.01 ml). pyridine (5.83 ml, 72.0 mmol) was added to the mixture followed by 4-methylbenzene-1-sulfonyl chloride (5.49 g, 28.8 mmol). The mixture stirred at roomtemperature overnight. Mixture was concentrated by roto-vap. Residue was dissolved in dichloromethane. Material was washed twice with saturated aqueous sodium bicarbonate. Combined aqueous layers were back-extracted with dichloromethane. Combined organics were washed twice with iN hydrochloric acidand once with brine. Organics were dried MgSO4, filtered and then concentrated todryness to get 2,5,8,11-tetraoxatridecan-13-yl 4-methylbenzenesulfonate (4.12 g, 11.37 mmol, 47.3 % yield) which was used as is in the next step.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 23783-42-8, 2,5,8,11-Tetraoxatridecan-13-ol.
