Abstract
The synthesis of some dipeptides which contain α-aminonitriles as their C-terminal residues is described. The coupling reactions of active esters of N-tritylamino acids, p-nitrophenyl esters or cyanomethyl esters, with α-aminonitriles were carried out in N,N-dimethylformamide. The N-trityl protecting groups of the reaction products were removed by acid hydrolysis without affecting their nitrile groups. In this way, glycylaminoacetonitrile acetate(8), glycyl-DL-α-aminopropionitrile acetate(10) and DL-alanylaminoacetonitrile acetate(11) were synthesized.Keywords
