Key Points

  • The study aims to develop a one-step photoredox-catalyzed hydroxyalkylation method for synthesizing β-amino alcohols from α-silylamines.
  • Photoredox-catalyzed hydroxyalkylation of nucleophilic α-silylamines with various electrophilic carbonyls.
  • Utilization of a polarity-matched strategy for substrate compatibility and late-stage modification.
  • Mechanistic investigations on the formation of α-amino radical through single-electron oxidative desilylation.
  • Successful synthesis of β-amino alcohols with high substrate and functional group compatibility.
  • One-step method demonstrated scale-up potential compared to classical multistep reactions.
  • Mechanistic studies confirm α-amino radical formation as a key step in the reaction process.

Abstract

A step-economic, photoredox-catalyzed hydroxyalkylation of nucleophilic α-silylamines with diverse electrophilic carbonyls to access biologically relevant β-amino alcohols. In contrast to the classical multistep Henry reaction, this one-step approach utilizes a polarity-matched strategy to directly forge the target scaffolds. This protocol features remarkable substrate/functional group compatibility, scale-up potential, and facile late-stage modification. Mechanistic studies reveal the formation of the α-amino radical from α-silylamines by a single-electron oxidative desilylation.
