Here, we report the selective, catalytic isomerization of cis-1,2-diols to trans-diequatorial-1,2-diols. The method employs triphenylsilanethiol (Ph3SiSH) as a catalyst and proceeds under mild conditions in the presence of a photoredox catalyst and under blue light irradiation. The method is highly chemoselective, broadly functional group tolerant and provides concise access to trans-diol products which are not readily obtained using other methods. Mechanistic studies reveal that isomerization proceeds through a reversible hydrogen atom transfer pathway mediated by the silanethiol catalyst.
Research in the Wendlandt Group focuses on the development of selective, catalytic reactions using the tools of organic/organometallic synthesis and physical organic chemistry.
