Some Extensions of von Braun (BrCN) Reaction on Organic Bases
نویسندگان
چکیده
von Braun Cyanogen Bromide Reaction Some extensions of von Braun cyanogen bromide reaction have been undertaken on conessine, isoconessine and two simpler bases, dimethyl a-naphthyl amine and diethyl amine. The monocyanamides of conessine and isoconessine yielded acid amides, aminoderivatives (diamines) and guanido derivatives on careful hydrolysis, reduction and treatment with ammonia, respectively. The simpler bases also formed the acid amides and diamines but failed to give the guanido derivatives under the conditions employed for conessine series. Diamines of all these bases yielded carbinol amines on reaction with nitrous acid.

Some Extensions of von Braun (BrCN) Reaction on Organic Bases: Part II
In an earlier communication Siddiqui and Bina [1] reported some extensions of von Braun BrCN reaction on the conessine series of alkaloids, which appeared to provide a novel route for the synthesis of therapeutically active nitrogenous compounds including substituted ureas, diamines, carbinol amines and guanidine derivatives. However, it was noted by them that dimethyl a-napthylamine and diethy...
