The intramolecular Curtiusrearrangement suffers from a high reaction temperature, low yields, tedious product isolation, and difficult scale up. This study presents a room-temperature Curtiusrearrangement 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

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.

A series of novel benzimidazole derivatives were synthesized and evaluated for their anti-hepatitis B virus (HBV) activity and cytotoxicity in the HepG2.2.15 cell line. The preliminary SAR was discussed. Compound 12a, with IC50 < 0.41 mu M and SI > 81.2, was the most promising compound and selected as the benchmark compound for further optimization.
