  Lewis Acid Catalyzed Unprecedented [3 + 2] Cycloaddition Yields 3,3′-Pyrrolidinyldispirooxindoles Containing Four Contiguous Chiral Stereocenters with Two Contiguous Quaternary Spirostereocenters

  摘要：

  A Lewis acid catalyzed domino reaction cascades through azide-alkene cycloadclition, rearrangement, aziridine ring opening, and azomethine cycloaddition with a parent dipolarophile, resulting in 3,3'-pyrrolidinyldispirooxindoles containing four contiguous chiral stereocenters with two contiguous quaternary spirostereocenters.

  Synthesis and biological evaluation of spiro[cyclopropane-1,3′-indolin]-2′-ones as potential anticancer agents

  摘要：

  Libraries of spiro[cyclopropane-1,3'-indolin]-2'-ones were synthesized and evaluated for their biological activity against five different human cancer cell lines HT-29 (colon cancer), DU-145 (prostate cancer), Hela (cervical cancer), A-549 (Lung cancer), and MCF-7 (breast cancer). Many compounds of the series exhibited promising anticancer activity (IC50 < 20 mu M) against the studied cell lines. Based on the screening results, a structure activity relationship (SAR) of the pharmacophore was proposed. Among the series compound 6b and 6u showed significant activity against human prostate cancer cell line, DU-145. Flow cytometric analysis showed that these two compounds arrested the cell cycle in the G0/G1 phase leading to caspase-3 dependent apoptotic cell death. Further, measurement of mitochondrial membrane potential and Annexin V-FITC assay also suggested that 6b and 6u induced cell death by apoptosis. (C) 2015 Elsevier Ltd. All rights reserved.

  cyclization pathway from difluorocarbene and ortho-amino aryl alkynone, rendering an effective and universal strategy for the construction of 3-alkenyl-2-oxindoles. Our strategy starts from cheap and accessible ortho-amino aryl alkynone instead of the direct indole skeleton; moreover, in situ generated difluorocarbene from commercially available halogenated difluoroalkylative reagents enables the cleavage

  在此，我们报道了一种来自二氟卡宾和邻氨基芳基炔酮的无过渡金属 [4 + 1] 环化途径，为构建 3-烯基-2-羟吲哚提供了一种有效且通用的策略。我们的策略从廉价易得的邻氨基芳基炔酮开始，而不是直接的吲哚骨架；此外，从市售的卤化二氟烷基化试剂中原位生成的二氟卡宾能够裂解 C-N 键并形成新的 C-N 键和 C-C 键。
