A late-stage functionalization tool: sulfonyl fluoride mediated deoxymethylation of phenols
ORGANIC & BIOMOLECULAR CHEMISTRY(2022)
摘要
The late-stage functionalization of drugs and natural products has been identified as a promising approach to accelerate the discovery of new bioactive compounds. Due to the presence of the "Magic Methyl Effect", the direct deoxymethylation of phenolic hydroxyl groups, which are widespread in natural molecules, is a challenging task. A mild and rapid strategy for direct phenol deoxymethylation under metal catalysis using SO2F2 is described in this paper, while good functional group tolerance and high chemoselectivity allow this strategy to be one of the powerful tools for LSF. The power of this new platform is showcased through gram-scale and orthogonal experiments.
