We report the first examples of radical cation Smiles rearrangements. A series of aryloxy alkylamines underwent spontaneous reaction, with the amino group displacing theipso-alkoxy group through substitution, at ambient temperature and under photoactivation by visible light in the presence of an acridinium catalyst (5 mol%). The study was extended to 3-(2-methoxyphenyl)propan-1-amine derivatives, which lack an appropriateipsoleaving group. Here, efficient cyclisations resulted in displacement of the methoxy group and formation of tetrahydroquinolines.

Abstract: The objective of this study is to investigate the antiproliferative and cytotoxic properties and the?action mechanism of substituted quinoline and tetrahydroquinolines 3, 4, 5, 7, and 8 against rat glioblastoma (C6), human cervical cancer (HeLa), human adenocarcinoma (HT29) cancer cell lines by BrdU Cell Proliferation ELISA, Lactate Dehydrogenase, DNA laddering and Topoisomerase I assays. The results of the study showed that 6,8-dibromotetrahydroquinoline 3 possess in vitro antiproliferative activity against C6, HeLa, and HT29 cell lines while morpholine/piperazine substituted quinoline 7 and 8 showed selective antiproliferative activity on C6 cell line with IC50 values 47.5 and 46.3?μg/mL, respectively. Moreover, 6,8-dibromoTHQ 3 caused DNA fragmentation while it did not inhibit the Topoisomerase I (Topo I) enzyme. On the other hand, compound?8 did not cause DNA laddering while 8 inhibited the Topo I enzyme. According to these results, 6,8-dibromoTHQ 3 stimulates apoptosis on the C6 cell line while 6,8-dibromo-3-morhonilylquinoline (8) inhibits the Topo I enzyme to cause antiproliferative activity.

Chemoselective One-Pot Synthesis of Functionalized Amino-azaheterocycles Enabled by COware

Functionalized bicyclic amino-azaheterocycles are rapidly accessed in a one-pot cross-coupling/reduction sequence enabled by the use of COware. Incompatible reagents are physically separated in a single reaction vessel to effect two chemoselective transformations - Suzuki-Miyaura cross-coupling and heteroarene reduction. The developed method allows access to novel heterocyclic templates, including semisaturated Hedgehog and dual PI3K/mTOR inhibitors, which show enhanced physicochemical properties compared to their unsaturated counterparts.
