Isopropenylboronic acid pinacol ester Usage And Synthesis

Description	Isopropenylboronic acid pinacol ester is a versatile ester reagent used for palladium-catalyzed Suzuki-Miyaura cross-coupling processes, inverse-electron-demand Diels-Alder reaction, Simmons-Smith cyclopropanation reaction, polyene cyclization, stereoselective aldol reactions, Grubbs cross-metathesis reaction, intramolecular Suzuki-Miyaura reaction, Stereoselective cross-metathesis, dipolar cycloaddition, iodosulfonylation, asymmetric conjugate addition and intramolecular hydroacylation and preparation of various therapeutic kinase and enzymatic inhibitors¹. It can be used as an intermediate in the synthesis of variety of cyclic and acyclic organic compounds. It is also shown that the α-Substituted Allyl/Croty of this compound can be used for highly Diastereo- and Enantioselective allylboration of aldehydes².
