A process for the production of (R)-3-hydroxybutyl (R)-3-hydroxybutyrate comprising: i) contacting poly-(R)-3-hydroxybutyrate with an alcohol to transesterify the poly-(R)-3-hydroxybutyrate under transesterification conditions to produce an ester of (R)-3-hydroxybutyrate and the alcohol; ii) separating the product of step i) into a first and second portion and reducing the first portion of the (R) 3-hydroxybutyrate ester to form (R)-1,3-butanediol; and iii) contacting under transesterification conditions the (R)-1,3-butanediol from step ii) with the second portion of the transesterified ester to produce (R)-3-hydroxybutyl-(R)-hydroxybutanoate.
一种生产(R)-3-羟基丁酸丁酯的方法,包括:i)将聚(R)-3-羟基丁酸酯与醇接触,在酯交换条件下酯交换聚(R)-3-羟基丁酸酯,以产生(R)-3-羟基丁酸丁酯和醇的酯;ii)将步骤i)的产物分为第一和第二部分,并还原(R)-3-羟基丁酸酯的第一部分以形成(R)-1,3-丁二醇;和iii)在酯交换条件下使步骤ii)中的(R)-1,3-丁二醇与酯交换后的第二部分接触,以产生(R)-3-羟基丁酸丁酯。
