, p. 849 - 852 (1995)
A new method for the resolution of racemic amines and its application to 3-amino-1,5-benzodiazepines is reported. The method is based upon the reaction of the amines with a chiral auxiliary, namely the tosyl derivative of (S)-(+)-methyl mandelate, followe
A chemical method for the preparation of novel 1,5-benzodiazepines acting as CCK-B antagonists in high enantiomeric purity
Curotto, Giovanni,Donati, Daniele,Finizia, Gabriella,Ursini, Antonella
, p. 7347 - 7364 (1997)
A series of new N-(1,5-benzodiazepin-3-yl)-N'-arylureas, 2, bearing an alkyl substituent at the N5 position of the benzodiazepine nucleus has been studied as potential CCK-B antagonists. The homochiral compounds were obtained by resolving their precursors

The synthesis of new (4S,8aS)- and (4R,8aS)-4-phenyl-perhydropyrrole[1,2-a]pyrazine-1,3-diones in the cyclocondensation reaction of the respective derivatives of l-prolineamide is described. The effect of the amount of NaOEt, temperature, and reaction time on the proportions of diastereomers formed in the cyclocondensation reaction was examined. The structures of the diastereomers were confirmed by GC/MS, HRMS, HPLC, XRD, and 1H and 13C NMR investigations.
