Patent number: 11884639Abstract: A field of asymmetric catalytic synthesis, and in particular a preparation method for a high optical indoxacarb intermediate includes reacting 5-chloro-2-methoxycarbonyl-1-indanone ester (or indanone ester for short) with an oxidizing agent in the presence of a chiral Zr-salen polymer to obtain an indoxacarb intermediate (2S)-5-chloro-2,3-dihydro-2-hydroxy-1-oxo-1H-indole-2-carboxylic acid methyl ester. The yield is stabilized between 86% and 90%, and the S-enantiomer content is up to 99%. Such catalyst can replace catalysts such as cinchonine, and greatly increase the content of the effective S-enantiomer of the indoxacarb, so that the content of the hydroxyl intermediate S-enantiomer of the indoxacarb is raised from 75% to 99% or more. In addition, the chiral Zr-salen polymer catalyst is recycled without retreatment, and can be recycled at least 5 times or more, greatly reducing the production cost and laying a foundation for the industrial production of high quality indoxacarb.Type: GrantFiled: April 25, 2019Date of Patent: January 30, 2024Assignee: SHANDONG JINGBO AGROCHEMICALS TECHNOLOGY CO., LTD.Inventors: Zhongyang Wang, Daoquan Cheng, Tingchao Pang, Ping Wang, Jiancheng Liu, Renping Han, Lianyou Yu, Nengchun Wei

Patent number: 11639336Abstract: A catalyst and a method for preparing S-indoxacarb using the catalyst. The catalyst is prepared using 3-tert-butyl-5-(chloromethyl)salicylaldehyde and cyclohexanediamine as raw materials, where an original quinine catalyst such as cinchonine is replaced with the catalyst for application in the asymmetric synthesis of tert-butyl hydroperoxide and 5-chloro-2-methoxycarbonyl-1-indanone ester, greatly improving selection in the asymmetric synthesis process, with the S-enantiomer content increasing from 75% to over 98%, achieving the recycling of a high-efficiency chiral catalyst, and greatly reducing production costs. The synthesis process of the catalyst is simple and is favorable for industrialization, and lays good foundations for the production of high-quality indoxacarb.Type: GrantFiled: April 25, 2019Date of Patent: May 2, 2023Assignee: SHANDONG JINGBO AGROCHEMICALS TECHNOLOGY CO., LTD.Inventors: Leifang Bo, Daoquan Cheng, Jiancheng Liu, Peiliang Feng, Huamin Liu, Zhongyang Wang
