  作为潜在的抗血管药物的6-甲氧基-3-（3'，4'，5'-三甲氧基苯甲酰基）-1H-吲哚（BPR0L075）的新双取代类似物的合成和生物学评估。

  摘要：

  6-甲氧基-3-（3'，4'，5'-三甲氧基苯甲酰基）-1H-吲哚（BPR0L075）（1）是微管蛋白聚合的有效抑制剂，对多种固体均表现出体内和体外活性肿瘤。该化合物被设计为康普他汀A4（CA-4）的杂环类似物，康普他汀A4是一种天然的二苯乙烯衍生物，可破坏肿瘤的脉管系统并导致肿瘤消退。在目前的工作中，我们描述了几种新的1的双取代类似物的设计和合成，以及它们作为潜在抗血管药物的生物学评估。化合物13在吲哚核的7位带有一个羟基，该羟基模仿CA-4 B环的3位上的羟基，被认为是微管蛋白聚合的有效抑制剂，也是亚微摩尔浓度的针对B16黑色素瘤细胞的细胞毒剂。此外，化合物13在纳摩尔浓度的内皮细胞（EA.hy 926细胞）上显示出明显的形态学活性（向上舍入），这表明潜在的抗血管活性。有趣的是，尽管在微管蛋白聚合抑制试验中具有中等活性，但在细胞测定中也发现了相应的7-O-甲磺酸酯衍生物28（13的合成

• Lewis Acid-Controlled Regioselectivity in Reactions of Styrenyl Systems with Benzoquinone Monoimides:  New Regioselective Syntheses of Substituted 2-Aryl-2,3-dihydrobenzofurans, 2-Aryl-2,3-dihydroindoles, and 2-Arylindoles
  作者：Thomas A. Engler、Wenying Chai、Kenneth O. LaTessa

  日期：1996.1.1

  Reactions of 4-(N-phenylsulfonyl)-2-alkoxy-1,4-benzoquinone monoimines 2-4 with electron-rich propenylbenzenes promoted by BF3 yield 7-alkoxy-2-aryl-3-methyl-5-[(N-phenylsulfonyl)amino]2,3-dihydrobenzofurans 5-7 nearly exclusively, whereas promotion of the reactions by Ti4+ gives mixtures of the dihydrobenzofurans and their N-(phenylsulfonyl)-6-alkoxy-2-aryl-5-hydroxy-3-methyl-2,3-dihydroindole isomers 8-10, depending upon substituents present on the propenylbenzene. However, reactions promoted with excess Ti4+, as mixtures of TiCl4:Ti(OiPr)(4), give the dihydroindoles as nearly the exclusive products. Evidence for a mechanism involving initial 5 + 2 cycloaddition of the Lewis acid-bound quinone monoimide with the propenylbenzene is found in reactions of styrenes 1f/g with monoimide 3 in which 7-aryl-3-hydroxy-6-methylbicyclo[3.2.1]oct-3-ene-2,8-diones 33 (5 + 2 adducts) are isolated. These reactions have been applied to stereoselective syntheses of pterocarpans bearing N-phenylsulfonyl groups, azapterocarpans and diazapterocarpans. In addition, DDQ oxidation of derivatives of several of the 2-aryl-2,3-dihydroindoles afford the corresponding 2-arylindoles in good yield. Finally, the experimental details of a general synthetic approach to 7-alkoxy-benzofuranoid neolignans, including (+/-)-licarin B and eupomatenoids-1 and -12 are reported.
