  The intramolecular Curtius rearrangement suffers from a high reaction temperature, low yields, tedious product isolation, and difficult scale up. This study presents a room-temperature Curtius rearrangement that can be novelly driven by the HFIP solvent, followed by light-illuminated intramolecular cyclization. Such a mild reaction allows for the preparation of various fused pyridone derivatives with

  分子内Curtius重排反应温度高、产率低、产物分离繁琐且难以放大。这项研究提出了一种可以由 HFIP 溶剂驱动的室温 Curtius 重排，然后进行光照射分子内环化。这种温和的反应允许制备具有不同取代基的各种稠合吡啶酮衍生物，这些取代基很少被以前的方法掺入。通过结合 IR 和 NMR 滴定的一组对照实验研究了 HFIP 和光的作用。此外，使用取代的融合吡啶酮作为非天然碱基，我们可以获得一组新的核苷酸。

  Twenty four compounds with diversified 3-aryl acrylic amide side chains of the simplified saframycin-ecteinascidin pentacyclic skeleton were synthesized via a 14-step stereospecific route starting from L-dopa. The cytotoxicities of these compounds were tested against eight human tumor cell lines including HCT-8, BEL-7402, BGC-803, A549, A2780, MCF-7, MX-1, and MDA-MB-231. Most of these compounds exhibited potent antitumor activity, and a preliminary structure-activity relationship (SAR) was discussed. Compound 28 with 3-thiophenyl acrylic amide side chain exhibited selective cytotoxicity against MDA-MB-231 cell line with the IC50 value of 50 nM. (C) 2013 Elsevier Masson SAS. All rights reserved.

  日期：2020.5.15

  Radical cation vinylcyclopropane rearrangements by TiO2 photocatalysis in lithium perchlorate/nitromethane solution are described. The reactions are triggered by oxidative single electron transfer, which is followed by immediate ring-opening of the cyclopropanes to generate distonic radical cations as unique reactive intermediates. This approach can also be applied to vinylcyclobutane, leading to the

  Two new arylpiperazine derivatives, the 4-(1-piperazinyl)thieno- and -furo[3,2-c]pyridine ring systems, have been synthesized and appended via tetramethylene chains to various imide rings. Target compounds from each series were found to have significant activity in the blockade of apomorphine stereotypy and apomorphine-induced climbing, the Sidman avoidance response, and the conditioned avoidance response
