Catalyst-Free Synthesis of Borylated Lactones from Esters via Electrophilic Oxyboration

[Image: see text] A catalyst-free oxyboration reaction of alkynes is developed. The resulting borylated isocoumarins and 2-pyrones are isolated as boronic acids, pinacolboronate esters, or potassium organotrifluoroborate salts, providing a variety of bench-stable organoboron building blocks for down...
