چکیده

3-Methyl-5-nitropyrimidin-4(3H)-one readily reacts with carbonyl compounds to produce three kinds of ring transformations. The nitropyrimidinone behaves as the synthetic equivalent of activated diformylamine affording 3,5-difunctionalized 4-pyridones, 4,5disubstituted pyrimidines and functionalized 4-aminopyridines. It also behaves like α-nitroformylacetic acid to give 5,6-disubstituted 3-nitro-2-pyridones.

Ring Cleavage of Some Bicylic Compounds Derived from 1,2,4-Triazine

Ring cleavage occurred when 1,2,4-triazino-1,2,4-triazines (3), (4) and (5) were treated with concentrated hydrochloric acid to yield N-substituted triazines (7) and (8). These confirm the given configuration assigned to the isomeric triazinotriazines. 6-Methyl-2-phenyl-7H-oxazolo [3,2-b][1,2,4]-triazin-7-one (9) underwent ring cleavage on treatment with sodium alkoxide to afford 3-alkoxy-1...

In the reaction of 7-chloro-1,5-benzodiazepine-2,4-dione with N,N-dimethyl-formamide/dimethyl-acetal, the diazepine seven-membered ring undergoes a contraction to form the five-membered ring. The reaction yields two isomers the title compound, C(13)H(14)ClN(3)O(2); the major component has the chlorine-atom substituent in the 5-position of the benzimidazolone ring and the minor component has the...

The title compound, C(20)H(19)N(3)O(3)·C(3)H(7)NO, was synthesized by the reaction of 6-amino-pyrimidine-2,4(1H,3H)-dione and 4-methyl-benzaldehyde with 5,5-dimethyl-1,3-cyclo-hexa-nedione in 1-butyl-3-methyl-imidazolium bromide at 363 K. The pyrimidine ring adopts a half-chair conformation while the six-membered ring fused to the pyridine ring adopts a skew-boat conformation. The dihedral angl...
