L. Charoy et al., Synthesis of benzylcyanoborane adducts of amines and separation of their enantiomers; S(N)2 substitution at boron atom, CHEM COMMUN, (22), 2000, pp. 2275-2276
Benzylcyanoborane adducts of several amines were prepared in four steps fro
m toluene, their enantiomers were separated using chiral phase HPLC and an
S(N)2 pathway was evidenced in the reaction of a trimethylamine-derived ena
ntiomer with pyridine.
