Platinum-catalyzed enantioselective 1,4-diboration of cyclic 1,3-dienes is reported, providing enantioenriched 1,4-bis(boronic) esters in good yield and up to 96:4 er. The analogous diboration reaction of imines generated enantioenriched alpha-amino boronic esters, which are valuable therapeutic candidates and useful synthetic building blocks. Alpha-substituted allyl bis(boronic) esters, which are derived from 1,2-diboration of 1,3-dienes, undergo double allylation with 1,4-dicarbonyls to afford cyclic 1,4-diols bearing four contiguous stereocenters in a one-pot fashion with moderate to excellent diastereoselectivity. The development of a synthesis of geminal bis(boronic) esters is disclosed. These unique compounds were utilized in an alkoxide-promoted deborylative alkylation to access primary, secondary and tertiary boronic esters.
