  • Patent number: 8372985
    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.
