SOME SIDE REACTIONS IN THE TEMPLATE SYNTHESIS OF MACROCYCLIC COMPOUNDS FROM o-AMINO-o'-HALOAZOPYRAZOLES

Article abstract of DOI:10.1007/BF00504115

Pyrazolo<4,5-d>-1,2,3-triazoles and 3,4-dimethyl-1,6-diphenyl-dipyrazolo<4,5-b:4',5'-c>-1,6-dihydropyridazine, the structures of which are confirmed by the mass and PMR spectra, were isolated as side products in the preparation of macrocyclic compounds by
