  Synthesis of Casimiroin and Optimization of Its Quinone Reductase 2 and Aromatase Inhibitory Activities

  摘要：

  An efficient method has been developed to synthesize casimiroin (1), a component of the edible fruit of Casimiroa edulis, on a multigram scale in good overall yield. The route was versatile enough to provide an array of compound 1 analogues that were evaluated as QR2 and aromatase inhibitors. In addition, X-ray crystallography studies of QR2 in complex with compound 1 and one of its more potent analogues has provided insight into the mechanism of action of this new series of QR2 inhibitors. The initial biological investigations suggest that compound 1 and its analogues merit further investigation as potential chemopreventive or chemotherapeutic agents.

  The synthesis of aryl amines via the formation of a C−N bond is an essential tool for the preparation of functional materials, active pharmaceutical ingredients and bioactive products. Usually, this chemical connection is only possible by transition metal-catalyzed reactions, photochemistry or electrochemistry. Here, we report a metal-free arene C−H amination using hydroxylamine derivatives under benign

  A modified version of the Bischler indole synthesis has been developed in which the key step is the N–H insertion reaction of rhodium carbene intermediates derived from α-diazo-β-ketoesters with anilines. Thus N-methylanilines 1 react with diazoketoesters 2 in the presence of dirhodium(II) acetate to give (N-arylamino)ketones 3, cyclisation of which using boron trifluoride–ethyl acetate or acidic ion exchange resin gives the indoles 4. In order to extend this method to the synthesis of N-unsubstituted indoles, a new protecting group strategy for indoles was developed. In this, anilines are reacted with α,β-unsaturated-esters or -sulfones to give the conjugate addition products 6 and 9, cyclisation of which gives indoles 8 and 11. The N-(2-ethoxycarbonylethyl)- and -(2-sulfonylethyl)- protecting groups are readily removed from indoles 8 and 11 by treatment with base.

  一种改进的Bischler吲哚合成方法已被开发，其中关键步骤是铑卡宾中间体从α-重氮-β-酮酯与苯胺的N-H插入反应。因此，N-甲基苯胺1与重氮酮酯2在二铑(II)醋酸盐存在下反应生成(N-芳氨基)酮3，使用三氟化硼-乙酸乙酯或酸性离子交换树脂进行环化反应得到吲哚4。为了将这种方法扩展到N-未取代的吲哚的合成，开发了一种新的吲哚保护基团策略。在此过程中，苯胺与α,β-不饱和酯或砜反应生成共轭加成产物6和9，其环化反应生成吲哚8和11。N-(2-乙氧羰基乙基)- 和 -(2-砜乙基)- 保护基团通过用碱处理从吲哚8和11中容易地去除。
