Goldberg, Mariano published the artcileFacile conversion of 1,2-dicyanobenzene into chiral bisamidines, Product Details of C8H4N2, the main research area is chiral bisamidine preparation; diarylethylene diamine dicyanobenzene nucleophilic catalysis acetyl cysteine catalyst.
Nucleophilic catalysis by N-acetyl cysteine permits the smooth reaction of 1,2-diarylethylene-1,2-diamines (R,R)/(S,S)-RCH(NH2)CH(NH2)R (R = Ph, 2-hydroxyphenyl, biphenyl-4-yl, naphth-1-yl, naphth-2-yl) with 1,2-dicyanobenzene forming chiral bisamidines I in yields up to 94% in a single step. Such bisamidines can be used as Bronsted bases or, in the protonated state, as electrophilic catalysts to promote Diels-Alder reactions with medium levels of enantioselectivity.
