  Carbene-Catalyzed α-Carbon Amination of Chloroaldehydes for Enantioselective Access to Dihydroquinoxaline Derivatives

  摘要：

  An NHC-catalyzed alpha-carbon amination of chloroaldehydes was developed. Cyclohexadiene-1,2-diimines are used as amination reagents and four-atom synthons. Our reaction affords optically enriched dihydroquinoxalines that are core structures in natural products and synthetic bioactive molecules.

  This invention aims at providing a catalyst for producing an optically active aldehyde or an optically active ketone, which is an optically active carbonyl compound, by carrying out selective asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, particularly a catalyst which is insoluble in a reaction mixture for obtaining optically active citronellal which is useful as a flavor or fragrance, by carrying out selective asymmetric hydrogenation of citral, geranial or neral; and a method for producing a corresponding optically active carbonyl compound. The invention relates to a catalyst for asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, which comprises a powder of at least one metal selected from metals belonging to Group 8 to Group 10 of the Periodic Table, or a metal-supported substance in which at least one metal selected from metals belonging to Group 8 to Group 10 of the Periodic Table is supported on a support, an optically active cyclic nitrogen-containing compound and an acid.

  In an effort to identify HDAC isoform selective inhibitors, we designed and synthesized novel, chiral 3,4-dihydroquinoxalin-2(1H)-one and piperazine-2,5-dione aryl hydroxamates showing selectivity (up to 40-fold) for human HDAC6 over other class I/IIa HDACs. The observed selectivity and potency (IC50 values 10–200 nM against HDAC6) is markedly dependent on the absolute configuration of the chiral moiety

  为了鉴定HDAC同工型选择性抑制剂，我们设计并合成了新颖的，手性的3,4-二氢喹喔啉-2（1 H）-one和哌嗪-2,5-二酮芳基异羟肟酸酯，它们显示出对HDAC的选择性（高达40倍）人类HDAC6优于其他I / IIa类HDAC。观察到的选择性和效价（针对HDAC6的IC 50值为10–200 nM）明显取决于手性部分的绝对构型，这表明在选择性HDAC同工型抑制中使用手性化合物的新可能性。
