Newly developed iron catalysts can synthesize tert-butyl esters that were difficult to synthesize from previous catalysts
Kyushu University of Japan announced on June 23, 2016 that it has successfully developed a highly active and highly chemically selective high activity iron catalyst for ester synthesis. Many previous studies have investigated ester synthesis methods using catalysts from the viewpoint of green chemistry. However, the raw materials that can be used in these methods are limited. Therefore, there is a strong desire in the industry to develop an ester catalyst synthesis method with a large steric hindrance effect.
The highly active iron catalyst developed this time enables the synthesis of esters from difficult raw materials. For example, it is possible to use a low-priced methyl ester to synthesize a tert-butyl ester that is useful in synthetic chemistry. Tert-butyl ester is very important for the synthesis of peptides and the synthesis of polymers such as polyesters.
In chemically selective reactions, active esters that require more precise control can also be used as raw materials. In addition, a variety of pharmaceutical products can also be used as raw materials to achieve selective hydroxylation of aromatic amino alcohols.
This catalyst is the core of green pharmaceutical research promoted by Kyushu University. At present, the calibration is carried out on the synthesis of pharmaceuticals harmless to people and the earth. The results of this study were published on the June 16, 2016 issue of the Chemistry-A European Journal (IF 5.7). (Special Contributor: Kudosuke)
