Title: Masato Katayama: Innovator in Optically Active Compounds
Introduction
Masato Katayama is a prominent inventor based in Nagoya, Japan. He has made significant contributions to the field of chemistry, particularly in the production of optically active compounds. With a total of seven patents to his name, Katayama's work has had a notable impact on various applications in agriculture and pharmaceuticals.
Latest Patents
One of Katayama's latest patents is a method for the production of optically active (+)-4,4,4-trifluoro-3-(indole-3-)butyric acid. This innovative method involves reacting 2,2,2-trifluoroethanol with a racemic modification of the acid, resulting in a reaction solution that contains the trifluoroethyl ester. An enzyme with esterase activity is then used to produce the optically active compound, which is subsequently separated from the reaction solution. Another significant patent involves indole-3-alkanoic acid derivatives, which serve as agents for increasing the sugar content and/or decreasing the acid content of plant fruits. This method allows for the application of a fluorine-containing β-indolebutyric acid compound to unripe fruits, promoting maturation with higher sugar content and lower acidity.
