The asymmetric unit of the title salt, C(7)H(9)N(2)O(2) (+)·Cl(-), contains two independent cations and anions. In the crystal, each N-methyl-4-nitro-anilinium cation is linked to two Cl(-) anions via N-H⋯Cl hydrogen bonds. π-π stacking is observed between the benzene rings of adjacent cations [centroid-to-centroid distances = 3.7684 (14) and 3.7917 (7) Å].

barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. their reduction with zinc and hydrochloric acid in methanol yielded the narylmethylcysteines ?9a-c?. these can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?reaction of n, n'-carbonyl diimidazole (im co...

Amidines with a trichloromethyl group exhibit the properties of inotropic agents, which are used as scaffolds in synthesizing aza-hete­rocycles and ligands for complex formation. Functionalized amidines show anticancer, antidiabetic activity, antihypertensive antiparasitic agents. The synthesis new functional derivatives such is definitely an urgent task. introduction alkenyl substituent severa...

haloalkyl purines i.e. 2,6-diamino-8-(chloromethyl) purine 10; 2, 6-diamino-x- (chloromethyl) purine 17; 2,6-diamino-8-(chloropropylp) urine 18; were synthesized by two distinct but facile methods. the n-alkylating potential of 2, 6-diamino-8- (chloromethyl) purine was investigated. the following products 2,6-diamino-8-(nbenzyl- n-methyl) purine 11; 2,6-diamino-8-(4-nitro anilinomethyl) purine ...
