Azoxystrobin intermediate compound B and compound C are synthesized from compound A in the present invention, which is catalyzed by using a trimethylamine catalyst, allowing the reaction to have high efficiency and high yield. In addition, the trimethylamine catalyst has a low boiling point and thus can be easily recycled so that the ammoniacal nitrogen content in wastewater can be reduced, and the difficulties and high costs for wastewater processing can be also reduced. The recycled trimethylamine catalyst can be reused in preparing intermediate compound B, which also has a high catalytic effect and can also achieve a high product yield.

Iodoarene derivative, method for manufacturing optically active spirolactone compound by using the same, and method for manufacturing optically active cycloadduct

Номер: US20130338364A1
Принадлежит: Nagoya University NUC

An optically active spirolactone compound is highly enantioselectively produced by using an iodoarene derivative which can be synthesized easily and which is not racemized easily. A hypervalent iodine compound precursor (iodoarene derivative) which was able to be designed flexibly was synthesized from 2,6-dihydroxyiodoarene by using 1,2-aminoalcohol as a chiral source in short steps, a hypervalent iodine compound was prepared in a reaction system (in situ) by using a catalyst quantity of the resulting precursor in the presence of a stoichiometric quantity of m-CPBA, and a spirolactonization reaction of 3-(1-hydroxy-2-naphthyl)propionic acid was induced. As a result, a corresponding spirolactone compound was obtained at a high enantiomeric excess.

Improved glycol acylation process with water-tolerant metal triflates

Номер: US20170008902A1
Принадлежит: Archer Daniels Midland Co

A method for acid-catalyzed acylation of an isohexide is described. The method can enable direct alcohol acylation with carboxylic acids. In particular, the method involves reacting an isohexide and an excess of carboxylic acid, in the presence of a water-tolerant Lewis acid catalyst. Water-tolerant Lewis acid catalysts can furnish relatively high diester yields (e.g., ≧55%-60%) at lower catalyst loads. This feature, among others, is highly desirable for cost savings, and can improve process economics.
