| titleOfInvention | A kind of preparation method of L-aminobutanedioic acid condensation product |
| abstract | The present invention relates to technical field of organic synthesis, more particularly to a kind of preparation method of L-aminobutanedioic acid condensation product, the preparation method to comprise the following steps：(1) with alcohol esterification occurs for L-aminobutanedioic acid, obtains L-aminobutanedioic acid diester；(2) benzyl ester of Boc L aspartic acids 1 is reacted with L-aminobutanedioic acid diester, obtains condensation product；(3) condensation product is hydrolyzed, produces the L-aminobutanedioic acid condensation product.The present invention is using L-aminobutanedioic acid and the benzyl ester of Boc L aspartic acids 1 as raw material, through being esterified, being condensed, hydrolyzing, isolating and purifying to obtain the L-aminobutanedioic acid condensation product of high-purity.The preparation method is adapted to more large batch of preparation in laboratory, good impurity removing effect in purge process. |
