Abstract

The 1,2-aminoalcohol motif is one of the most prevalent structural components found in high-value organic molecules, including pharmaceuticals and natural products. Generally, its preparation requires pre-functionalized substrates and manipulations of one functional group at a time to achieve the desired regioisomer. Herein, we describe a metal-free photosensitization protocol for the installation of both amine and alcohol functionalities into alkene feedstocks in a single step. This approach is enabled by the identification of oxime carbonate as a suitable bifunctional source of both oxygen- and nitrogen-centred radicals for addition across alkenes with complementary regioselectivity compared to Sharpless aminohydroxylation. Use of orthogonal protection for amine and alcohol functionalities enables the direct synthe
