Abstract
A catalyst- and additive-free, visible-light-induced O-H insertion reaction of diazo compounds produces valuable α-hydroxy and α-alkoxy esters in good yields. The protocol exhibits a broad substrate scope and good functional-group tolerance. Notably, a gram-scale synthesis has been performed in a photochemical continuous-flow mode.
