    DMSO–PdI2 as a powerful oxidizing couple of alkynes into benzils: one-pot synthesis of nitrogen-containing five- or six-membered heterocycles
    摘要:
    PdI2 in DMSO promoted the oxidation of functionalized diarylalkynes into benzil derivatives in excellent yields. This new oxidation reaction was achieved with short reaction times and low loading of palladium catalyst. This efficient catalytic process has been applied successfully to the one-pot construction of a series of nitrogen-containing heterocycles of biological interest according to a tandem oxidation-nitrogen nucleophiles condensation-cyclization.

    铜催化的脱丙酮 Sonogashira 偶联
    摘要:
    已经开发了一种方便的无钯和无膦方案,用于从叔炔丙醇和(杂)芳基卤化物组装内部炔烃。所提出的串联方法包括碱基促进的逆向 Favorskii 裂解,然后是铜催化的 C(sp)–C(sp 2 ) 交叉偶联。使用廉价的试剂(例如催化剂、添加剂、碱和溶剂)和良好的官能团耐受性使该程序实用且具有成本效益。该方法的合成效用通过源自天然甾体激素的乙烯基碘化物的平滑炔基化得到证实。
