Reduction of Tertiary Carbon Radicals via Asymmetric Hydrogen Atom Transfer (AHAT)†

Comprehensive Summary In the past two decades, the development of asymmetric radical reactions has achieved tremendous progress, which has emerged as a powerful tool for the synthesis of chiral molecules in synthetic chemistry. Among the diverse array of radical processes, the transfer of hydrogen atoms to tertiary carbon radicals offers the potential for constructing chiral tertiary carbon centers in a stereoselective fashion. Notwithstanding the challenges associated with the reactive and evanescent nature of radical species, the use of chiral reagents or mediators has enabled the stereocontrol of the asymmetric hydrogen atom transfer ( AHAT ), which provides novel avenues for advancing the field of asymmetric synthesis.
