    Molecular iodine-catalyzed C3-alkylation of 4-hydroxycoumarins with secondary benzyl alcohols
    摘要:
    A highly efficient method for the C-C bond formation via molecular iodine-catalyzed C3-alkylation reaction of 4-hydroxycoumarins with benzylic, benzhydrylic, allylic, and propargyl alcohols at 50 degrees C in MeNO2 is described. The 3-alkylated-4-hydroxycoumarins were obtained in good yields (up to 97%). By applying this reaction as the key step, a multi-substituted pyranocoumarin can easily be synthesized in a one-pot procedure. The advantages of this method are broad scope, mild conditions, and easy handling since water is the only side product. (C) 2009 Elsevier Ltd. All rights reserved.

    In an endeavor to provide an efficient route to natural product hybrids, described herein is an efficient, highly stereoselective, one‐pot process comprising an organocatalytic conjugate addition of 1,3‐dicarbonyls to α,β‐unsaturated aldehydes followed by an intramolecular isocyanide‐based multicomponent reaction. This approach enables the rapid assembly of complex natural product hybrids including
    为了提供一种通往天然产物杂种的有效途径,本文描述了一种高效,高度立体选择性的单锅法,该方法包括将1,3-二羰基加至α,β-不饱和醛的有机催化共轭加成反应,然后进行分子内异氰酸酯加成反应。基于多组分的反应。这种方法能够快速组装复杂的天然产物杂种,包括多达四个不同的分子片段,例如氢喹啉酮,色烯,哌啶,肽,脂质和糖苷部分。该策略将有机催化的立体控制与多组分反应产生多样性的特征相结合,从而导致结构独特的拟肽药物整合了杂环,脂质和糖部分。
