Synthesis of New Macrocyclic Schiff Bases Containing Pyrazole and Triazole as Subcyclic Units

The novel macrocyclic Schiff bases upon which were fused triazole and pyrazole units and containing N, O and S inside the macrocyclic ring as donor atoms were synthesized by condensation of appropriate bis(4‐amino‐1,2,4‐triazole‐3‐yl‐sulfanyl)alkanes 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i, 2j, 2k, 2l, 2...

Summary:The novel macrocyclic Schiff bases upon which were fused triazole and pyrazole units and containing N, O and S inside the macrocyclic ring as donor atoms were synthesized by condensation of appropriate bis(4‐amino‐1,2,4‐triazole‐3‐yl‐sulfanyl)alkanes 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i, 2j, 2k, 2l, 2m, 2n, 2o, 2p, 2q, 2r and pyrazoledialdehyde 3 in refluxing glacial acetic acid. The structural identities of these compounds were confirmed on the basis of spectrum.
