Brief introduction of 171290-52-1

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 171290-52-1, name is 3,5-Dimethoxyphenylacetylene, A new synthetic method of this compound is introduced below., HPLC of Formula: C10H10O2

Formula 7 of the azide compound (300 mumol), alkynyl (750 mumol), CuSO4 (9.6 mg, 60 mumol) and Na. An ascorbate (60.0 mg, 300 mumol) 1: was dissolved in 1 t-BuOH / H2O (3 mL). The mixture was stirred at room temperature for 2 hours. After the reaction was completed, the mixture was filtered of and washed using H2O (70 mL) (solid A). The filtrate was extracted with EtOAc (3 ¡Á 70 mL). The combined organic extracts were then dried using anhydrous MgSO4, filtered and concentrated by rotaryevaporation (residue B). It was combined and the solid residue A and B, was purified by column chromatography to give the compound of formula 2 and 3. Following the general method for the general formula 2, 1: 1 t-BuOH / H2O (3 mL) in a compound 7b (76.7 mg, 300 mumol), -3,5- dimethoxybenzene (121 mg 1-ethynyl, 750 mumol), CuSO4 (9.6 mg, 60 mumol) and Na. Using ascorbate (60.0 mg, 300 mumol) was prepared in the desired compound. The reaction mixture was stirred at room temperature for 48 hours, was purified by column chromatography (5: 1 hexane / EtOAc ? 20: 1 CH2Cl2 / MeOH) Compound 2b was obtained by using as a brown solid (90.6mg, 73%).

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
