00925njm 22002777a 4500 dc Roscales García, Silvia author García Csaky, Aurelio author 2015 The transition-metal-free intermolecular direct 1,2-carboboration reaction of heteroarylacetylenes using boronic acids as reagents is achieved by utilizing tartaric acid as promoter. 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. Roscales, Silvia, y Aurelio G.
