    The development of a new decarboxylative cross‐coupling method that affords terminal and substituted alkynes from various carboxylic acids is described using both nickel‐ and iron‐based catalysts. The use of N‐hydroxytetrachlorophthalimide (TCNHPI) esters is crucial to the success of the transformation, and the reaction is amenable to in situ carboxylic acid activation. Additionally, an inexpensive

    calculations revealed that solvent affects the reaction pathway. In basic solvents (DMF, NMP, DMSO), N,N-bis(oxy)enamines were converted into nitrosoalkenes by a Lewis base promoted process followed by oxy-Michael addition of the HO-acid. In non-polar solvents (toluene, CH2Cl2), the reaction occurs by an acid-promoted SN′ substitution of the N-oxy-group via a highly reactive N-vinyl-N-alkoxynitrenium species.
    已发现将 HO-酸添加到 N,N-双(氧)烯胺中活化的 π 键的区域选择性极大地取决于溶剂。机理研究和量子化学计算表明,溶剂会影响反应途径。在碱性溶剂(DMF、NMP、DMSO)中,N,N-双(氧)烯胺通过路易斯碱促进的过程转化为亚硝基烯烃,然后是 H2O 酸的氧迈克尔加成。在非极性溶剂(甲苯、CH2Cl2)中,反应通过酸促进的 N-氧基团的 SN' 取代通过高反应性的 N-乙烯基-N-烷氧基硝基物质发生。基于这些研究,开发了使用现成的 N,N-双(氧)烯胺对各种 HO-酸(羧酸、酚类、异羟肟酸、磷酸和磺酸)进行肟基烷基化的通用和有效方案。这些方法被证明适用于带有酸性 OH 基团(如甾体激素、胆汁酸、受保护的氨基酸和肽)和配体 (BINOL) 的天然分子的后修饰。所得α-羟基肟被证明是有价值的1,2-氨基醇或1,2-羟基氨基醇衍生物的有用前体,包括抗心律失常药物美西律和有效的基质金属蛋白酶抑制剂。
