Discovery of a Novel Series of Biphenyl Benzoic Acid Derivatives as Potent and Selective Human β<sub>3</sub>-Adrenergic Receptor Agonists with Good Oral Bioavailability. Part I
A novel class of biphenyl analogues containing a benzoic acid moiety based on lead compound 8i have been identified as potent and selective human beta 3 adrenergic receptor (beta 3-AR) agonists with good oral bioavailability and long plasma half-life. After further substituent effects were investigated at the terminal phenyl ring of lead compound 8i, we have discovered that more lipophilic substitution

We report on the use of visible light photoredox catalysis for the radical Smilesrearrangement of 2-aryloxybenzoic acids to obtain aryl salicylates. The method is free of noble metals and operationally simple and the reaction can be run under mild batch or flow conditions. Being a redox neutral process, no stoichiometric oxidants or reductants are needed.
