Research in the field of functionally substituted azines. Syntheses of imidazolidinyl-sym-triazines

New approaches have been developed for the application of cyanamino-sym-triazines in the synthesis of imidazolidinyl-sym-triazines.     

Synthesis of N-cyano-N-alkoxycarbonylalkylamino-symm-triazines and their solvolysis

The action of potassium salts of cyanoamino-symm-triazines on esters of chloroacetic and bromomalonic acids gave carbonylalkylamino-symm-triazines. The solvolysis of these esters proceeds with heterocyclilzation, leading to the formation of hydantoin derivatives.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1114–1116, August, 1993.     

Synthesis of Isatin and 5-Bromoisatin Derivatives

New N-derivatives of isatin were synthesized by treating ethyl chloroacetate, N-(2-chloroethyl)morpholine, and 1,4-di(chloromethyl)benzene with isatin sodium salt. N-Derivatives of isatin and 5-bromoisatin were also prepared by Mannich reaction.
