Synthesis of 1,2-amino alcohols by decarboxylative coupling of amino acid derived α-amino radicals to carbonyl compounds <i>via</i> visible-light photocatalyst in water
coupling reaction of N-aryl amino acids with aldehydes or ketones for the synthesis of various 1,2-amino alcohols by using water as the solvent at room temperature is described. This protocol is characterised by broad substrate scopes, mild reaction conditions and amenability to gram-scale synthesis, which opens up a simple, mild but effective method to produce 1,2-amino alcohols from readily available
decarboxylative coupling of amino acids with aldehydes. A series of 1,2-amino alcohols are accessed in a transition-metal-free fashion under eco-friendly and redox-neutral conditions. The application of an urushiol-derived film in visible-lightphotoredoxcatalysis is also disclosed.
