  Chloramphenicol base chemistry. Part 11: 1 chloramphenicol base-derived thiourea-catalyzed enantioselective Michael addition of malononitrile to α , β -unsaturated ketones

  摘要：

  The first chloramphenicol base-derived thiourea-catalyzed enantioselective Michael addition of malononitrile to alpha,beta-unsaturated ketones is reported. The Michael adducts were obtained in good to excellent yields (up to 98% yield) and enantioselectivities (up to 94% ee). This reaction has a broad substrate scope to various alpha,beta-unsaturated ketones. With this in mind, this methodology was successfully applied to the synthesis of a chiral piperidone, an advanced building block for dihydropyridinone P2X(7) receptor antagonists.

  An efficient enantioselective conjugate addition of malononitrile to a range of β-substituted 2-enoylpyridines catalyzed by cinchona alkaloid-based bifunctional urea catalysts has been developed. Both enantiomers of the products could be achieved with the same level of enantioselectivity by using pseudoenantiomeric catalysts in up to 97% ee and in excellent yields. One of the enantioenriched products

  已经开发了将丙二腈有效地对映选择性共轭加成到由金鸡纳生物碱基双功能尿素催化剂催化的一系列β-取代的2-烯丙基吡啶上。通过使用假对映异构体催化剂以高达97％ee的产率和优异的收率，可以在相同的对映体选择性水平下获得两种产品的两种对映体。对映体富集的产物之一已被转化为高度官能化的哌啶酮衍生物。

  The catalytic enantioselective Michael addition of α,β-unsaturated ketones with malononitrile was well established using rare-earth metal amides RE[N(SiMe3)2]3 (RE = Y, Eu, Sm, Nd, La) with chiral phenoxy-functionalized TsDPEN ligands. The combination of lanthanum amide La[N(SiMe3)2]3 and chiral TsDPEN ligand H3L1 [H3L1 = N-((1R,2R)-2-((3,5-di-tert-butyl-2-hydroxybenzyl)amino)-1,2-diphenylethyl)-4
