Barbiturates 3 as possible antimicrobialagents were obtained by reacting the N,N′‐disubstituted urea 1a or the thiourea analogues 1b,c with the magic malonates 2a,b. On the other hand, reaction of 1a with ethoxycarbonyl isocyanate (4) yielded the substituted s‐triazine‐2,4,6(1H,3H,5H)‐trione 5. The reaction of 4 with 2‐aminomethyl‐benzimidazole (6) gave the allophanate 7 which upon treatment with
