  A rapid and diverse construction of 6-substituted-5,6-dihydro-4-hydroxy-2-pyrones through double Reformatsky reaction

  摘要：

  A rapid and diverse synthesis of biologically important 6-substituted-5,6-dihydro-4-hydroxy-2-pyrones through a double Reformatsky reaction of aldehydes to delta-hydroxy-beta-ketoesters followed by lactonization is described. Due to the high functional group tolerance and reaction site discrimination between aldehyde, nitrile, and ester groups in the substrate, the protocol can provide the dihydropyrones with bromo, nitro, carboxylic acid, and beta-ketoester groups, which are suitable for the further derivatizations. Furthermore, the protocol has been successfully applied to the rapid total synthesis of naturally occurring Yangonin. (C) 2013 Elsevier Ltd. All rights reserved.

  一锅烯醇硅烷形成-Mukaiyama Aldol反应：交叉的醛-醛偶联，硫代酯底物和酯溶剂中的反应

  摘要：

  三甲基甲硅烷基三氟甲磺酸盐（TMSOTf）和三烷基胺碱可在单个反应瓶中促进原位烯醇硅烷/甲硅烷基烯酮缩醛的形成和Mukaiyama aldol加成反应。不需要分离所需的烯醇硅烷或甲硅烷基烯酮缩醛。例如，α-二取代的醛与不可烯化的醛之间的交叉醇醛缩合反应以良好的产率产生β-羟基醛。在相关的反应中，普通的实验室溶剂乙酸乙酯既充当烯醇化物前体又充当绿色反应溶剂。当使用硫酯作为烯醇化物前体时，常规观察到高产率地加成到不可烯化的醛中。

  An efficient, economical, and practical Reformatsky reaction of α-halo carbonyl compounds with aldehydes/ketones by using cheap and commercial iron(0) powder as reaction mediator is developed. The reactions proceeded effectively in the presence of a catalytic amount of iodine (20 mol %) to afford the synthetically useful β-hydroxyl carbonyl compounds in moderate to good yields.

  An efficient and simple Cu-catalyzed Reformatsky reaction of ketones and aldehydes has been accomplished with ethyl iodoacetate. Excellent yields of β-hydroxyl esters were achieved with a range of ketones and aldehydes, which varied from aromatic to aliphatic, unsaturated to saturated ketones and aldehydes. This practical and convenient transformation was conducted with inexpensive, readily available
