The reaction proceeds with excellent regioselectivity and anti stereoselectivity to afford boroxole frameworks. The resulting compounds are of use for the stereoselective preparation of polysubstituted alkenylheteroarenes.engTransition-Metal-Free Direct anti-Carboboration of Alkynes with Boronic Acids To Produce Alkenylheteroarenesjournal articlehttps://doi.org/10.1021/acs.orglett.5b00517restricted access547Química orgánica (Química)2306 Química Orgánica
