combination of hypervalent iodine(III) reagents (HIR) and photoredox catalysis with visible light has enabled chemoselective decarboxylative ynonylation to construct ynones, ynamides, and ynoates. This ynonylation occurs effectively under mild reaction conditions at room temperature and on substrates with various sensitive and reactive functional groups. The reaction represents the first HIR/photoredox dual
高价碘(III)试剂(HIR)和光氧化还原催化与可见光的结合,使化学选择性脱羧酰基化反应能够构建出炔酮,酰胺和壬酸酯。在室温下,在温和的反应条件下,在具有各种敏感和反应性官能团的底物上,该酰化反应有效地发生。该反应代表了第一个由α-酮酸形成酰基自由基的HIR /光致氧化还原双重催化,然后是前所未有的将酰基自由基加到与HIR结合的炔烃上的过程。它在中性水性条件下可有效构建mGlu5受体抑制剂,这表明了未来可见光诱导的生物学应用。
