  • Pd(II)-Catalyzed Synthesis of Alicyclic[<i>b</i>]-Fused Pyridines via C(sp<sup>2</sup>)–H Activation of <i>α,β</i>-Unsaturated <i>N</i>-Acetyl Hydrazones with Vinyl Azides

    日期:2022.1.7
    A new synthetic protocol for alicyclic[b]-fused pyridines with complete regioselectivity from α,β-unsaturated N-acetyl hydrazones and vinyl azides via Pd(II)-catalyzed C–H activation/cyclization/aromatization strategy has been described. A series of five- to eight-membered alicyclic[b]-fused pyridines were prepared in a one-step manner with wide substrate scope and good functional group tolerance.

  • Three-component Reaction of Cycloheptanone, 6-Amino-1,3-Dimethyluracil and Aromatic Aldehydes; X-Ray Structure, and Anti-inflammatory Evaluation of the Products

    1,3-Dimethyl-5-aryl-1,6,7,8,9,10-hexahydrocyclohepta[5,6]pyrido[2,3-d]pyrimidine-2,4-diones 4a, b (the linear regioisomers) and the Schiff bases, 6-N-benzylidenamino-1,3-dimethyluracil derivatives 5a, b, were isolated from a three-component reaction of cycloheptanone, 6-amino-1,3- dimethyluracil, and 4-chloro- or 4-bromobenzaldehyde. Surprisingly, 1,3-dimethyl-10-aryl-1,5,6,7, 8,9-hexahydrocyclohepta[4,5]pyrido-[2,3-d]pyrimidine-2,4-diones 6f, g (the angular regioisomers which are described for the first time in the literature under the given reaction conditions) and the Schiff bases, 6-N-benzylidenamino-1,3-dimethyluracil derivatives 5f, g, were isolated and characterized from the reaction with 4-methoxybenzaldehyde and 4-cyanobenzaldehyde. However, the three-component reaction of 6-amino-1,3-dimethyluracil, cycloheptanone, and 2-methoxybenzaldehyde afforded 1,3-dimethylbenzo[4,5]pyrido[3,2-d]pyrimidine-3,4-dione (7). Single crystal X-ray diffraction and 13C NMR studies of 4a and 6f provided support for the established structures. Some of the new products were tested for antiinflammatory activity comparable to indomethacin.

    1,3-二甲基-5-芳基-1,6,7,8,9,10-六氢环庚[5,6]吡啶[2,3-d]嘧啶-2,4-二酮4a、b(线性异构体)和席夫碱,6-苄基亚甲基-1,3-二甲基尿嘧啶衍生物5a、b,从环庚酮、6-氨基-1,3-二甲基尿嘧啶和4-氯苯甲醛或4-溴苯甲醛的三组分反应中分离得到。令人惊讶的是,1,3-二甲基-10-芳基-1,5,6,7,8,9-六氢环庚[4,5]吡啶-[2,3-d]嘧啶-2,4-二酮6f、g(在给定的反应条件下首次在文献中描述的角异构体)和席夫碱,6-苄基亚甲基-1,3-二甲基尿嘧啶衍生物5f、g,从与4-甲氧基苯甲醛和4-氰基苯甲醛的反应中分离和表征。然而,6-氨基-1,3-二甲基尿嘧啶、环庚酮和2-甲氧基苯甲醛的三组分反应产生了1,3-二甲基苯并[4,5]吡啶[3,2-d]嘧啶-3,4-二酮(7)。对4a和6f的单晶X射线衍射和13C NMR研究支持了已建立的结构。一些新产品被测试其抗炎活性,与消炎症素相当。

  • Regioselective Synthesis of Dispirocycloalkanooxindolopyrrolidines and Dispirocyclalkanoindanopyrrolidines
    作者:Mahalingam Poornachandran、Mathesan Jayagobi、Raghavachary Raghunathan
    DOI:10.1080/00397910903004373
    日期:2010.2.2
    Synthesis of a series of novel dispirocycloalkanone-oxindolopyrrolidines and dispirocycloalkanone-indanopyrrolidines is described. The nonstabilized azomethine ylides generated from a secondary amino acid, sarcosine, and carbonyl components (isatin and ninhydrin) have been effectively trapped by the dipolarophiles, arylidene cycloalkanones, to afford dispiropyrrolidines. The one-pot azomethine ylide cycloaddition reactions were highly regioselective.
