Synthesis of enantiopure C2-chiral amidines
Dauwe,Buddrus
, p. 171 - 172 (1995)
Starting from optically active 1,2-diamines the optically active C2-chiral amidines 3a-e and 4a,b were prepared.
Palladium-catalyzed multicomponent synthesis of 2-aryl-2-imidazolines from aryl halides and diamines
Geden, Joanna V.,Pancholi, Alpa K.,Shipman, Michael
, p. 4158 - 4164 (2013/05/22)
An efficient palladium-catalyzed three-component reaction that combines aryl halides, isocyanides, and diamines provides access to 2-aryl-2-imidazolines in yields up to 96%. Through variation of the diamine component, the reaction can be extended to the s
Fractional crystallisation of (±)-iso-amarine with mandelic acid: convenient access to (R,R)- and (S,S)-1,2-diamino-1,2-diphenylethanes
Braddock, D. Christopher,Hermitage, Stephen A.,Redmond, Joanna M.,White, Andrew J.P.
, p. 2935 - 2937 (2007/10/03)
(±)-iso-Amarine can be conveniently resolved via 1:1 salt formation with either hand of mandelic acid. Enantiopure iso-amarine can be acetylated and hydrolysed to give enantiopure 1,2-diamino-1,2-diphenylethanes.
A mild and efficient one-pot synthesis of 2-dihydroimidazoles from aldehydes
Fujioka, Hiromichi,Murai, Kenichi,Ohba, Yusuke,Hiramatsu, Atsushi,Kita, Yasuyuki
, p. 2197 - 2199 (2007/10/03)
The reactions of various aldehydes and 1,2-diamines followed by NXS treatment proceed at 0°C-rt to give the corresponding dihydroimidazoles in high yields. The reaction is mild, and many functional groups such as halogens, nitriles, and esters can exist.
