  • Method for producing geometrical isomer of oximino compound
    Patent number: 10710977
    Abstract: Provided is a novel process for selectively producing the E-geometrical isomer or Z-geometrical isomer of an oximino compound useful as a medicine or agrochemical. In the process, a mixture of geometrical isomers of an oximino compound represented by formula (EZ)-1 is mixed with an acidic compound to produce the E-isomer of the oximo compound represented by the formula (E)-1 or the Z-isomer of the oximino compound represented by the formula (Z)-1 in high yields with high stereoselectivity.
    Type: Grant

  • Crystal forms of sulfonylurea compound and method for producing the same
    Patent number: 8765640
    Abstract: Crystal forms of sulfonylurea compound and method for producing the same. It has been found that a sulfonylurea compound of Formula (1): has two types of crystal polymorphisms and four types of pseudo crystal polymorphisms. A production method of each crystal form of the sulfonylurea compound of Formula (1) through recrystallization or solvate has been also found. In addition, a suspension of a composition containing the crystal that is improved in storage stability is provided.
