  • Publication number: 20100099915
    Abstract: The present invention is directed to a process of making ?-aminooxyketone and ?-hydroxyketone compounds. The synthetic pathway generally involves reacting an aldehyde or ketone substrate and a nitroso substrate in the presence of a catalyst of the formula (IV): wherein Xa—Xc represent independently nitrogen, carbon, oxygen or sulfur and Z represents a 4 to 10-membered ring with or without a substituent and optionally a further step to convert the ?-aminooxyketone compound formed to the ?-hydroxyketone compound. The present invention results in ?-aminooxyketone and ?-hydroxyketone compounds with high enantioselectivity and high purity. The present invention is also directed to a catalytic asymmetric O-nitroso Aldol/Michael reaction. The substrates of this reaction are generally cyclic ?,?-unsaturated ketone substrate and a nitroso substrate.

  • Publication number: 20100036153
    Abstract: The invention at hand provides at least dinitroxylated diamantanes. In addition, it provides methods for producing substituted diamantanes with high yields and selectivity. According to the invention, dinitroxylated diamantanes are suitable for being reacted with nucleophiles to form the corresponding disubstituted diamantanes. Surprisingly, it was discovered that at least dinitroxylated or hydroxylated diamantanes are rearranged in the presence of a strong acid, creating at least 4,9-nitroxylated or hydroxylated diamantanes. On the basis of this, 4,9-substituted diamantanes are able to be produced in a targeted manner by reaction with further nucleophiles.

  • Patent number: 7622420
    Abstract: This invention provides a catalyst composition for preparing hydroxylamine, which comprises palladium, a platinum compound, a germanium compound and a carrier, wherein a halogen concentration of the composition is no more than 10 ppm. The catalyst composition is prevented from poisoning by halogens, and therefore the catalyst composition has high selectivity and catalytic activity. Further, the weight ratio of palladium and platinum in the catalyst composition ranges from 100:1 to 1000:1, such that the catalyst composition can be used to solve the commonly observed problem, i.e., decreased selectivity due to the excessive amount of platinum.

  • Patent number: 7491846
    Abstract: It is an object of the present invention to provide a process for producing a hydroxylamine by reacting a salt of hydroxylamine with an alkali compound, where the yield reduction due to formation of a complex between the produced hydroxylamine and a salt produced as a by-product or adsorption of the hydroxylamine to the by-product salt is decreased, and a high-concentration and high-purity hydroxylamine is safely produced at a high yield. The process for producing a hydroxylamine of the present invention comprises a reaction step of reacting a salt of hydroxylamine with an alkali compound to obtain a hydroxylamine while keeping the reaction solution at a pH of 7 or more, a purification step of purifying the hydroxylamine by ion exchange, and a concentration step of concentrating the hydroxylamine by distillation at the column bottom.
