Abstract

Official abstract text for this publication.

A process for producing an optically active 2-alkyl-1,1,3-trialkoxycarbonylpropane (2), comprising a step of asymmetric hydrolysis of 2-alkyl-1,1,3-trialokoxycarbonylpropane (1) by using an enzyme capable of selectively hydrolyzing an ester moiety of either one enantiomer of 2-alkyl-1,1,3-trialkoxycarbonylpropane (1), or by using a culture of a microorganism capable of producing the enzyme or a treated object thereof.

First claim

Opening claim text (preview).

The invention claimed is: 1. A process for producing an optically active 2-alkyl-1,1,3-trialkoxycarbonylpropane of Formula (2): wherein: R 1 , R 2 and R 3 , which may be the same or different, are a C1-C4 alkyl group; and * represents an asymmetrical center; comprising hydrolyzing a 2-alkyl-1,1,3-trialokoxycarbonylpropane of Formula (1): wherein R 1 , R 2 and R 3 are as defined above, by contacting the 2-alkyl-1,1,3-trialkoxycarbonylpropane represented by Formula (1) with a culture of a microorganism, wherein the microorganism comprises an enzyme capable of selectively hydrolyzing an ester moiety of either one enantiomer, wherein the enzyme comprises the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 3, to provide the optically active 2-alkyl-1,1,3-trialkoxycarbonylpropane of Formula (2). 2. The process according to claim 1 , wherein R 1 is methyl. 3. The process according to claim 1 , wherein R 2 is methyl. 4. The process according to claim 1 , wherein R 3 is methyl. 5. The process according to claim 1 , wherein both R 1 and R 2 are methyl. 6. The process according to claim 1 , wherein both R 2 and R 3 are methyl. 7. The process according to claim 1 , wherein R 1 , R 2 and R 3 are methyl. 8. The process according to claim 1 , wherein the enzyme comprises the amino acid sequence of SEQ ID NO: 1. 9. The process according to claim 1 , wherein the enzyme comprises the amino acid sequence of SEQ ID NO: 3.
