J. Kurita et al., Resolution of racemic Sb-chiral stibindoles using an optically active ortho-palladated benzylamine derivative, via their diastereomeric complexes, CHEM COMMUN, (3), 2000, pp. 191-192
Resolution of racemic Sb-chiral (+/-)-1-phenyl-2-trimethylsilylstibindole 1
has been achieved by the separation of a mixture of the diastereomeric pal
ladium(ii) complexes 3A and 3B derived from the reaction of (+/-)-1 with di
-mu-chlorobis{(S)-2-[1-(dimethylamino)ethyl]phenyl-C,N}dipalladium(ii) 2, a
nd optically pure 1-phenylstibindoles (-)-4 and (+)-4 have also been obtain
ed from resolved (-)-1 and (+)-1, respectively.
