  A Novel, Convenient Synthesis of the 3‐O‐β‐D‐ and 4′‐O‐β‐D‐Glucopyranosides of trans‐Resveratrol

  摘要：

  trans-Resveratrol-3-O-beta-D-glueupyranoside (trans-piceid, 2) and trans-resveratrol-4'-O-beta-D-glucupyranoside (trans-resveratroloside 3) are the naturally occurring O-glucoside conjugates of the polyphenolic stilbenoid trans-resveratrol 1. Recently, attention has been drawn towards the interesting biological properties of the glucoside conjugates 2 and 3 as well as those of the aglycone 1. The fact that only limited quantities can be obtained by extraction from natural sources has prompted the development of novel syntheses of 2 and 3, based on a convergent Heck-coupling strategy, which now conveniently allows for the preparation of multimilligram to gram quantities of each.

  Synthesis of d-glucose and l-phenylalanine substituted phenylene–thiophene oligomers

  摘要：

  Phenylene-thiophene oligomers bearing peracetylated beta-D-glucose or N-BOC-L-phenylalanine as chiral substituents were synthesized in good yields by a versatile protocol based on the Suzuki-Miyaura cross-coupling reaction. Aryl iodides bearing the chiral biomolecules as substituents efficiently reacted with pinacol boronates of bi- or terthiophenes leading to the bio-functionalized oligomers in good yields.

  日期：2015.8.7

  A general Pd-catalyzed double carbonylation of aryl iodides with secondary or primary amines to produce α-ketoamides at atmospheric CO pressure has been developed. This transformation proceeds successfully even at room temperature and in the absence of any ligand and additive. A wide range of aryl iodides and amines can be coupled to the desired α-ketoamides in high yields with excellent chemoselectivities

  integration of amidyl radicals with cross-coupling chemistry opens new avenues for reaction design. However, the lack of efficient methods for the generation of such radical species has prevented many such transformations from being brought to fruition. Herein, the amidoarylation of unactivated olefins by a cascade process from non-functionalized amides is reported by merging, for the first time, photoredox

  酰胺基自由基与交叉偶联化学的整合为反应设计开辟了新途径。然而，缺乏产生此类自由基物种的有效方法阻止了许多此类转化的实现。在本文中，首次报道了通过光氧化还原质子偶联电子转移（PCET）与镍催化的合并，通过级联法从非官能化酰胺进行的未活化烯烃的酰胺化。这项新技术可以在可见光催化剂和镍催化剂的存在下，从烯基酰胺，芳基和杂芳基卤化物中获得一系列包含特权吡咯烷酮核心的复杂分子。值得注意的是，该反应不限于酰胺-也可以使用氨基甲酸酯和脲。机理研究，
