  A novel method for the synthesis of 3,4-disubstitutedpyrrole-2,5-dicarboxylates from hydrazones derived from α-diazo esters

  摘要：

  Hydrazones obtained from alpha-diazo esters were converted to pyrroles when heated with thionyl chloride in alcohol. Among hydrazones, those substituted with a benzene ring on the beta-carbon to the ester are likely to give pyrroles in good yields. (C) 2013 Elsevier Ltd. All rights reserved.

  日期：2012.1.11

  An asymmetric N-H insertion of α-diazoesters with anilines catalyzed by well-defined copper complexes of chiral spiro bisoxazoline ligands was studied in detail. The copper-catalyzed asymmetric N-H insertion of a wide range of α-alkyl-α-diazoacetates with anilines was accomplished with excellent enantioselectivity (up to 98% ee) and provided an efficient method for the preparation of optically active

• New Entry for Synthesis of N-Acylhydrazones, Pyridazinones, and 1,3,4-Oxadiazin-6-ones from .ALPHA.-Amino Acid Esters

  Versatile electrophiles N-acylhydrazones are synthesized via diazotization, reduction, and acylation of α-amino acid esters. Reduction of diazo esters with L-selectride® or tributylphosphine affords the corresponding hydrazones in good yields. Both reducing agents give anti-hydrazones as the major product although the reactivity of each reductant is slightly different. The resulting hydrazones are acylated to give N-acylhydrazones, which are subjected to further reactions to give 1,3,4-oxadiazin-6-ones that serve as useful synthetic intermediates for the Diels–Alder reaction.

  通过对 α-氨基酸酯进行重氮化、还原和酰化，可合成多功能亲电体 N-酰肼。用 L-selectride® 或三丁基膦还原重氮酯，可以得到相应的肼，而且收率很高。尽管每种还原剂的反应性略有不同，但两种还原剂都会产生主要产物反肼。生成的肼经酰化后可得到 N-酰肼，再经进一步反应可得到 1,3,4-恶二嗪-6-酮，它们是 Diels-Alder 反应的有用合成中间体。
• Novel method for synthesis of aryl hydrazones from α-diazo esters: scope and limitations of nucleophiles

  Aryl hydrazones, the precursor of Fischer indole synthesis, were easily obtained by nucleophilic addition of aryllithium reagents to diazo esters. The aryl hydrazones were converted into indoles in good yields by heating with thionyl chloride in alcohol. Grignard reagent was also a good nucleophile, whereas organozinc reagent did not react with diazo esters. Aryllithium reagents were prepared by reacting

  通过芳基锂试剂向重氮酯的亲核加成，很容易获得费歇尔吲哚合成的前体芳基hydr。通过与亚硫酰氯在醇中加热，将芳基酮以良好的产率转化为吲哚。格氏试剂也是良好的亲核试剂，而有机锌试剂则不会与重氮酯反应。芳基锂试剂是通过使在2-，3-，4-或多位具有各种取代基的芳基溴化物与n- BuLi反应制得的。将衍生自溴吡啶的亲核试剂加到重氮酯中也得到。

  The readily available low-valent iron complex [Fe(CO)3NO]− catalyzes the efficient transfer of carbenes to isocyanides. The resulting ketenimines undergo in situ cyclocondensation with various bisnucleophiles to give a broad range of medicinally relevant heterocycles. A plausible mechanism for the carbene transfer is proposed based on DFT calculations.
