synthesis of boron heterocycles from borinic and boronic esters with α-aminoacids was explored as a means of upgrading the optical purities of intermediates from asymmetric hydroboration. B-Methoxy-9-borabicyclo[3.3.1]nonane, methyl dicyclohexylborinate and (+)- and (-)-methyl diisopinocampheylborinate react with various α-aminoacids to form the corresponding crystalline chelates.
