  Rapid preparation of (methyl)malonyl coenzyme A and enzymatic formation of unusual polyketides by type III polyketide synthase from Aquilaria sinensis

  摘要：

  (Methyl) malonyl coenzyme A was rapidly and effectively synthesized by a two-step procedure involving preparation of N-hydroxysuccinimidyl (methyl) malonate from (methyl) Meldrum's acid, and followed by transesterification with coenzyme A. The synthesized (methyl) malonyl coenzyme A could be well accepted and assembled to 4-hydroxy phenylpropionyl coenzyme A by type III polyketide synthase from Aquilaria sinensis to produce dihydrochalcone and 4-hydroxy-3,5-dimethyl-6-(4-hydroxyphenethyl)-2H-pyrone as well as 4-hydroxy-3,5-dimethyl-6-(5-(4-hydroxyphenyl)-3-oxopentan-2-yl)-2H-pyrone.
