A 2 - (2-allyl) pentene-4-acid methyl ester preparation method (by machine translation)

The invention relates to a machine intermediate 2 - (2-allyl) pentene-4-acid methyl ester preparation method, the preparation method is as follows: step 1) malonic acid ring (inferior) of potassium hydroxide in isopropyl acetate under alkaline conditions by PEG-400 catalytic and 3-polybromide propylene reaction produce compound 1 ; step 2) compound 1 under alkaline conditions in the sodium hydroxide of hydrolyzed to generate β-b acid compound 2 ; step 3) β-b acid compound 2 is heated and a single carboxyl the carboxyl group lives 3 ; step 4) single carboxyl compound 3 is obtained by reacting the methyl ester of the methyl esterification of compound 4 ; step 5) methyl ester compound 4 under alkaline conditions in and again LDA 3-polybromide propylene reaction produce the target compound 5. In the method for preparing the raw materials of the malonic acid ring a (sub) and isopropyl acetate 3-polybromide propylene, low cost, small synthetic process step, the operation is simple, convenient extraction and purification, the yield can reach 80% or more.
