Copper-Photocatalyzed 1,2-Boron Migrative Alkylation of β-Boryl NHPI Esters with Cyclopropanols.
Organoboron compounds are highly useful compounds in chemical synthesis, and boron-migration chemistry has recently attracted substantial interest. Herein, we report a radical 1,2-boron migrative alkylation achieved by combining photocatalysis and copper catalysis. The β-boryl NHPI esters undergo a 1,2-boron shift to a...
