The current study involved synthesis of several new N-Substituted -
 3- chloro -2- azetidinones for 2,4-Diamino-6-phenyl-1,3,5-triazine by two
 steps. first step includes preparation Schiff bases (Al-A6) by
 condensation 2,4-Diamino-6-pheny]-1,3,5-triazine with many substituted
 aldehydes, then the second six azetidinone
 compounds (B1-B6) reaction acetyl chloride the&#...

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) pur...

This search involved synthesis of several new N-Substituted -3-chloro-
 2-azetidinones which were known as a high medicinal effectiveness for 2,
 4-Diamino-6-hydroxy pyrimidin in two steps. The first step included
 preparation Shiff bases (1-6) by condensation 2, 4-Diamino-6-hydroxy
 with many substituted aldehydes(4-hydroxy benzaldehyde, 2-
 bromobenzaldehyde, 4-dimeth...
