N,N-DIMETHYLCHLOROFORMIMINIUM CHLORIDE IN THE SYNTHESIS OF HETEROCYCLIC COMPOUNDS. THE SYNTHESIS OF N-HETEROARYLFORMAMIDINE HYDROCHLORIDES, OXAZOLO/5,4-D/PYRIMIDINES, FUSED IMIDAZOLES AND OTHER SYSTEMS

N,N-Dimethylchloroformiminium chloride (DCFC) was used for preparation of N-heteroarylformamidine hydrochlorides (2), fused oxazoles (4), imidazoles (6,8) and thiazoles (10).DCFC is advantageous in those cases in which the undesired further methylation of NH, OH, and SH groups could occur by using N,N-dimethylformamide dimethyl acetal (DMFDMA).

N-Heteroarylformamide oximes 3 (R = H) were converted with N,N-dimethylformamide dimethyl acetal (DMFDMA) into N-heteroaryl-N-methylcyanoamino compounds 5, as the main products.In some instances N-heteroarylcyanoamino compounds 4, cyanoimino compounds 7, and some other products, such as 9 and 10 were also formed.On the other hand, N-heteroarylacetamide oximes 3 (R = CH3) were cyclized under the same reaction conditions into 2-methyl-s-triazoloazines (6).N-Heteroarylacetamide O-methyl oximes 11 and 12 were prepared from the corresponding acetamidines 2 (R = CH3) and O-methylhydroxylamine.
