  acid/base-free domino process is developed for the regioselective synthesis of 1,2,4-trisubstituted pyrroles. The process involves 1,3-dipolar cycloaddition of unsymmetrical azomethine ylide resulting from the thermal C–C bond cleavage of unactivated aziridines with β-bromo-β-nitrostyrene, followed by a cascade of elimination and aromatization reaction sequence to preferentially furnish 1,2,4-trisubstituted

  开发了一种新的单锅，过渡金属，无酸/无碱的多米诺骨牌工艺，用于区域选择性合成1,2,4-三取代的吡咯。该过程涉及不对称的偶氮甲内酯的1,3-偶极环加成反应，这是由于未活化的氮丙啶与β-溴-β-硝基苯乙烯的热C–C键裂解所致，随后是一系列消除和芳构化反应序列，优先提供1,2 1,4-三取代的吡咯代替预期的1,2,3-三取代的吡咯，收率良好至极佳。此外，描述了该方法用于形式的宁格林B的合成。

  日期：——

  A metal-free approach for the synthesis of 7-membered aza-heterocycles has been developed by the intermolecular [5 + 2] cycloaddition of non-activated vinylaziridines and alkynes. This method has a broad substrate scope under mild reaction conditions to afford structurally diverse 7-membered N-heterocycles in high yield up to 92%.

  A convenient synthesis of α-(aziridin-2-yl)-α-(trifluoromethyl) alcohols starting with ethyl aziridine-2-carboxylates is reported. Grignard reaction with the corresponding Weinreb amides led to aziridin-2-yl ketones, and subsequent treatment with Ruppert-Prakash reagent gave the trimethylsilylated target compounds as mixtures of diastereoisomers, which were desilylated with TBAF. In the case of ethyl

  据报道，以氮丙啶-2-羧酸乙酯为起始原料，可以方便地合成α-（叠氮基-2-基）-α-（三氟甲基）醇。格氏反应与相应的Weinreb酰胺反应生成叠氮基-2-基酮，随后用Ruppert-Prakash试剂处理，得到三甲基甲硅烷基化的目标化合物，为非对映异构体的混合物，并用TBAF进行了甲硅烷基化。在1-（（S）-1-苯基乙基）氮丙啶-2-羧酸乙酯的情况下，获得（S，S）-和（S，R）-叠氮基-2-基酮，色谱分离并转化为所需的对映体纯的α-三氟甲基化醇。
