Kinetic resolution of 1-methyl- and 1-phenyl-3-amino-1,2-dicarba-closo-dodecaboranes via acylation with chiral acyl chlorides

A study of the kinetic resolution of racemic I-substituted 3 -amino- 1,2-dicarba-closo-dodecaboranes by chiral acyl chlorides has shown that N-tosyl-(S)-prolyl and N-phthaloyl-(S)-alaninyl chlorides are more efficient resolving agents than (S)-naproxen chloride.
