  Enantioselective Tandem O-Nitroso Aldol/Michael Reaction

  摘要：

  This communication presents studies that illustrated nitroso Diels-Alder adduct has been obtained in uniformly high enantioselectivity via a tandem nitroso aldol/Michael reaction using an amine catalyst. The regiochemical outcome of this construction is documented to be the opposite to that of the normal nitroso aldol reaction, which has been determined by X-ray analysis. The reaction of the enone with silver-BINAP catalyst has also been investigated in conjunction with the control of regiochemistry in a stepwise process.

  The present invention is directed to a process of making α-aminooxyketone and α-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 X a —X c 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 α-aminooxyketone compound formed to the α-hydroxyketone compound. The present invention results in α-aminooxyketone and α-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 α,β-unsaturated ketone substrate and a nitroso substrate. This methodology generally involves reacting the cyclic α,β-unsaturated ketone substrate and the nitroso substrate in the presence of a proline-based catalyst, to provide a heterocyclic product.

  本发明涉及一种制备α-氨氧基酮和α-羟基酮化合物的方法。合成途径通常涉及在催化剂存在下反应醛或酮底物和亚硝基底物，所述催化剂的公式为（IV）：其中Xa-Xc分别独立表示氮、碳、氧或硫，Z表示具有或不具有取代基的4到10个成员环，并可选择进一步步骤将形成的α-氨氧基酮化合物转化为α-羟基酮化合物。本发明的结果是具有高对映选择性和高纯度的α-氨氧基酮和α-羟基酮化合物。本发明还涉及一种催化不对称O-亚硝基Aldol/Michael反应。该反应的底物通常为环状α,β-不饱和酮底物和亚硝基底物。该方法通常涉及在脯氨酸基催化剂存在下反应环状α,β-不饱和酮底物和亚硝基底物，以提供杂环产物。
