Abstract

The invention belongs to the technical field of antibiotic production, and particularly relates to application of immobilized carboxyester hydrolase in side chain synthesis of cloxacillin, diclocillin, flucloxacillin and oxacillin. Compared with a traditional hydrolysis method of strong bases (KOH, NAOH), the application has the following advantages: firstly, the hydrolysis condition is mild, andis generally room temperature; secondly, the yield is very high and can reach more than 98%; thirdly, the cost is relatively low, and the economic benefit is remarkable; fourthly, due to high yield, the quantity of byproducts and sewage is extremely small; and fifthly, the immobilized carboxyester hydrolase can be reused.

Description

technical field [0001] The invention belongs to the technical field of antibiotic production, and particularly relates to the application of an immobilized carboxyl ester hydrolase in the synthesis of cloxacillin, dicloxacillin, flucloxacillin and oxacillin side chains. Background technique [0002] The traditional side chain synthesis of cloxacillin, dicloxacillin, flucloxacillin and oxacillin generally uses strong alkali (KOH, NAOH) hydrolysis, and the traditional method has several disadvantages. Higher; 2. The yield is not high, the highest not exceeding 85%; 3. The cost is relatively high. Contents of the invention [0003] The invention provides an application of an immobilized carboxyl ester hydrolase in the synthesis of cloxacillin, dicloxacillin, flucloxacillin and oxacillin side chains, which can solve the problems pointed out in the background technology. [0004] A kind of application of immobilized carboxyl ester hydrolase in cloxacillin, dicloxacillin, flucl...
