HETEROCYCLIZATION REACTIONS WITH CARBODIIMIDES: SYNTHESIS OF FUSED 1,2,4-TRIAZOLES

Several N-amino heterocycles react with diaryl carbodiimides under neutral conditions to give fused 1,2,4-triazoles.In some cases the intermediate heteroaryl guanidines are isolated, which by termal or basic treatment cyclized to neutral or mesoionic fused 1,2,4-triazoles.

A number of triazolotriazine derivatives have been prepared. 6-Methyl-3-methylthio-4-triphenylphosphoranylideneamino-5-oxo-4,5-dihydro-1,2,4-triazine (19) reacts with aryl isocyanates to yield the corresponding 1,3-diaryl-2,4-bis-(6-methyl-3-methylthio-5-oxo-4,5-dihydro-1,2,4-triazin-4-ylimino)-1,3-diazetidines (20)-(24); these undergo ring cleavage on treatment with aqueous ethanol to give the 8-aryl-7-arylamino-3-methyltriazolotriazin-4(8H)-ones (8), (12), and (16)-(18).The reaction of the 3-arylmethylenehydrazino-6-methyl-5-oxo-4-triphenylphosphoranylideneamino-4,5-dihydro-1,2,4-triazines (35) and (36), available from the corresponding 4-amino-3-arylmethylenehydrazino-6-methyl-5-oxo-4,5-dihydro-1,2,4-triazine and triphenylphosphine dibromide, with alkyl or aryl isocyanates led directly to 7-arylamino-8-arylmethyleneamino-3-methyltriazolotriazin-4(8H)-ones (37)-(46).Also, iminophosphoranes (5)-(7), (35), and (36) react with acyl chlorides in the presence of triethylamine to give the triazolotriazinones (25)-(31) and (50)-(55) respectively.Structures of compounds (20)-(24) have been established by means of (13)C n.m.r. analysis and X-ray crystallography.
