In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 25016-12-0 as follows. Recommanded Product: 25016-12-0
General procedure: Aldehyde (1.0 equiv) is a dissolved in anhydrous methanol (0.2-0.5 mM) and charged with cesium carbonate (1.0 equiv) and cooled to 0-5 oC . Dimethyl (1-diazo-2-oxopropyl)phosphonate (1.0 equiv) is added dropwise after which the reaction is allowed to stir for 1-18h after which the crude mixture is concentrated onto silica gel and purified directly by flash silica gel chromatography to provide the desired alkyne J-1.
According to the analysis of related databases, 25016-12-0, the application of this compound in the production field has become more and more popular.
