Preparation of racemic 2,3-diaminobutane and the resolution of its (2S,3S) enantiomer
Scaros, Mike G.,Yonan, Peter K.,Laneman, Scott A.,Fernando, Peter N.
, p. 1501 - 1506 (1997)
A three-step procedure for large scale preparation of pure racemic 2,3-diaminobutane from relatively inexpensive meso 2,3-butanediol is described. Also, an efficient method for the resolution of (S,S) 2,3-diaminobutane from the racemic mixture in 95% ee has been developed.
Titanium Induced Coupling of Imines to Symmetrical Vicinal (R*,R*)-Diamines
Mangeney, P.,Tejero, T.,Alexakis, A.,Grosjean, F.,Normant, J.
, p. 255 - 257 (2007/10/02)
Symmetrical vicinal (R*,R*) -d,l-diamines were prepared from the corresponding imines and low valent titanium species generated by the action of titanium tetrachloride on amalgamated magnesium.
