Adding a certain compound to certain chemical reactions, such as: 1871-57-4, name is 3-Chloro-2-chloromethyl-1-propene, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1871-57-4, SDS of cas: 1871-57-4
General procedure: To a cooled solution (5 C) of the corresponding 4,6-O-(R)-benzylidene-d-hexopyranoside derivative (obtained using the procedure describe by our group2c) (35.4 mmol) in dry THF (70 mL) were added, successively, freshly powdered potassium hydroxide (7.0 g, 125 mmol), 18-crown-6 (0.38 g, 1.4 mmol), and 3-chloro-2-chloromethylpropene (4.1 mL, 35.4 mmol). The reaction mixture was stirred at this temperature for 3 h, and left at room temperature until all the starting material had been consumed, as monitored by TLC (5-7 days, approximately), then diluted with dichloromethane (60 mL) and washed successively with water and aqueous saturated solution of sodium bicarbonate, dried (MgSO4), filtered, and the filtrate was evaporated to dryness.
