Stereoselective Synthesis of cis-β-Methyl- and Phenyl-Substituted Alkenylboronates by Platinum-Catalyzed Dehydrogenative Borylation

Stereoselective Synthesis of cis-β-Methyl- and Phenyl-Substituted Alkenylboronates by Platinum-Catalyzed Dehydrogenative Borylation

Changing places: Intramolecular B(pin)/H exchange took place in the presence of a platinum-phosphane catalyst, giving synthetically useful cis-β-methyl-substituted alkenylboronates stereoselectively (see scheme; B(pin)=4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl).
