    Gold-Catalyzed 1,3-Transposition of Ynones
    摘要:
    An efficient, regioselective gold-catalyzed 1,3-transposition reaction of ynones and diynones has been developed. It was found that stereoelectronic (interrupted conjugation) and electronic (extended conjugation) factors could efficiently govern the regioselectivity of this thermodynamically controlled transformation. The produced conjugated diynones were efficiently transformed into diverse alkyne-substituted five- and six-membered heterocycles.

    highlighted in the palladium‐catalyzed aminocarbonylation, alkoxycarbonylation, carbonylative Sonogashira coupling, and carbonylative Suzuki–Miyaura coupling of aryl halides. A variety of amides, esters, (hetero)aromatic ynones, and bis(hetero)aryl ketones were synthesized in good‐to‐excellent yields in a one‐pot fashion.
    羧基-MIDA-硼酸酯的应用(MIDA = N-甲基亚氨基二乙酸)作为各种催化转化的原位CO替代物进行了描述。先前曾证明,羧基MIDA硼酸酯是合成硼酸杂环化合物的长凳稳定的含结构单元。本研究表明,羧基-MIDA-硼酸酯除了可用作杂环合成的前体外,它还是一种出色的原位CO替代物,可耐受胺,醇和碳基亲核试剂等反应性功能。在催化的基羰基化,烷氧基羰基化,羰基化的Sonogashira偶联和芳基卤化物的羰基化的Suzuki-Miyaura偶联中,突出了其广泛的官能团相容性。各种酰胺,酯,(杂)芳族炔酮
