  The reaction of aryl iodides with alkyl 4-hydroxy-2-alkynoates in the presence of formic acid, tri-n-butylamine and a palladium(II) catalyst provides a convenient route to functionalized substituted butenolides through a one pot hydroarylation/cyclization reaction. In the presence of formic acid, tri-n-butylamine and a palladium(II) catalyst, alkyl 4-hydroxy-2-alkynoates undergo a one pot hydrogenation/cyclization

  在甲酸，三正丁胺和钯（II）催化剂的存在下，芳基碘化物与4-羟基-2-链烷酸烷基酯的反应提供了通过一锅加氢芳基化/环化反应制备官能化取代丁烯化物的便捷途径。在甲酸，三正丁胺和钯（II）催化剂的存在下，烷基4-羟基-2-链烷酸酯经过一锅加氢/环化反应生成丁烯内酯环。通过增加过量的甲酸，可以观察到饱和γ-内酯的直接形成。以高的立体选择性进行反应，并且在加氢芳基化的情况下，具有良好的区域选择性。

  Neutral organic electron-donor 7, formally a pyridinylidene carbene dimer, effects reductive cleavage of C−O σ-bonds in acyloin derivatives Ar(CO)CRR′OX (X = OAc, OPiv, OBz, OMs) and this represents the first cleavage of C−O σ-bonds by a neutral organic electron-donor. The methodology is applicable to a large array of substrates and the reduced counterparts were isolated in good to excellent yields

  中性有机电子给体7（通常为吡啶基亚苄基卡宾二聚体）实现酰氯衍生物Ar（CO）CRR'OX（X = OAc，OPiv，OBz，OMs）中CO键的还原裂解，这是首次裂解中性有机电子给体对C-Oσ键的影响。该方法学适用于大量的底物，并且还原的对应物以良好至极好的产率被分离出来。对于某些底物，供体7起碱的作用，与酰基辅酶的一些乙酸酯衍生物进行缩合反应，生成丁烯内酯。不同底物之间反应性的变化是合理的。

  Convenient and general Hg(II)/Pt(IV) catalyzed syntheses of γ-butyrolactams and α,β-unsaturated γ-butyrolactones/lactams are described via intramolecular electrophilic cyclizations of bromoalkynes with tosylamino and hydroxyl tethers. The reaction features the use of wet solvents, the exclusion of any base and additive, mild conditions and practical yields. We also synthesised few chiral lactams through

  通过溴炔烃与甲苯磺酰氨基和羟基束缚剂的分子内亲电环化反应，描述了常规且常规的Hg（II）/ Pt（IV）催化的γ-丁内酰胺和α，β-不饱和γ-丁内酯/内酰胺的合成。该反应的特征在于使用湿溶剂，不包含任何碱和添加剂，温和的条件和实用的收率。我们还通过该途径合成了一些手性内酰胺。另外，显示出距同炔丙基位置更远的NHS基团有助于区域选择性溴炔水合以产生有用的α-溴代酮。此外，Boc保护的溴高炔丙基胺经历了6-内切 通过Boc氧环化，得到溴亚甲基取代的oxazinones。

  The sequential rhodium-catalyzed addition/lactonization reaction of organoboron derivatives to alkyl 4-hydroxy-2-alkynoates would constitute a novel methodology for the synthesis of 4-aryl/heteroaryl/vinyl-2(5H)-furanones with an excellent control of the regio- and chemoselectivity. The role played by rhodium precatalyst, ligands, reaction medium, and the feature of organoboron derivatives has been
