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.
Novel reductive coupling of aldimines to vicinal diamines
Baruah, Bipul

Reductive coupling of aldimines into vicinal diamines has been performed by the action of aluminium/bismuth powder and potassium hydroxide in methanol at ambient temperature in high yields.
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.

Studies have been carried out on reations of condensation of aliphatic 1,2-diamines with 2,2'-dichlorodiethyl ether.It has been established that in the case of 1,2-diaminopropane and 2,3-diaminobutane appropriate derivatives of morpholine are formed, while in the case of their N,N'-dialkyl derivatives formation of alkyl substituted octahydro-1,4,7-oxadiazonines takes place.When some amines possessing aromatic substituents (N,N'-dibenzylethylenediamine, N,N'-dimethylstilbenediamine) at α carbon atom are used as substrates, derivatives of imidazoline are formed.
