Boron turns out to be a stable stereogenic center in iminecomplexes of aryl and alkyl boronates. Diastereomerically pure complexes 7a–c are obtained from chiral imine ligands 5a,b that are derived from the amino alcohol (R)-4. The configuration at the boron atom is determined by crystal structure analyses. Racemic boronates 10a–c, available from a condensation of aryl boronic acids 6 with the achiral
