Ammonium iodide-promoted unprecedented arylsulfonylation of quinone with sodium arylsulfinates
摘要:
A novel ammonium iodide-promoted arylsulfonylation of quinones with sodium arylsulfinates has been explored. This reaction proceeded smoothly through unique nucleophilic addition reaction and produced the arylsulfonylation products in moderate to good yields. The reactions proceeded efficiently over a broad range of substrates with good regioselectivity and functional group tolerance. (C) 2017 Elsevier Ltd. All rights reserved.
The electrochemical in-situ oxidative sulfonylation of phenols with sulfinicacids access to sulfonylated hydroquinones has been developed. A series of sulfonylated hydroquinones were prepared under mild mediator-, catalyst- and exogenous-oxidant-free conditions. Notably, such an electrochemical in-situ-oxidative synthetic strategy presented wide functional group tolerance and amenability to gram-scale

A series of analogs of 2-tosylnaphthalene-1,4-diol were prepared and were found to be potent 10-20 nM reversible inhibitors of the Escherichia coli FabH enzyme. The inhibitors were also effective but to a lesser degree (30 nM-5 mu M), against the Mycobacterium tuberculosis and Plasmodium falciparum FabH enzymes. Preliminary SAR studies demonstrated that the sulfonyl group and naphthalene-1,4 diol were required for activity against all enzymes but the toluene portion could be significantly altered and leads to either modest increases or decreases in activity against the three enzymes. The in vitro activity of the analogs against E. coli FabH parallel the in vivo activity against E. coli TolC strain and many of the compounds were also shown to have antimalarial activity against P. falciparum.
