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. 110104-60-4, name is (E)-Methyl 4-chloro-3-methoxybut-2-enoate, A new synthetic method of this compound is introduced below., Safety of (E)-Methyl 4-chloro-3-methoxybut-2-enoate
Genera procedure: To a solution of the corresponding alkyl amine (1.2 equiv) in THF (2.0 M) was added simultaneously a solution of (E)-4-chloro-3-methoxy-but-2-enoic acid methyl ester (1 equiv) in acetonitrile (1.5 M) and a solution of triethylamine (1 equiv) in acetonitrile (3.6 M) over 30 min at room temperature. After stirring overnight at room temperature or 3 h at 55 C, the resulting precipitate in the reaction mixture was removed by filtration. The mother liquor was concentrated and purified by flash chromatography on silica gel eluting with a gradient of 20-100% ethyl acetate in hexanes to afford the title compound in greater than 75% yield.
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.
