ring transformation affording two main entities 3-hydroxy-2- ethyl­ : I benzpyrimidine-4-one 2 and benzpyrid-4-one-2- oxime 3. Some selected . I I fused, bearing and spiro heterocyclic compounds were synthesisedibased on the latter heterocyclic transformed. On the other hand, so e 1 novel heterocyclic cyanine dyes incorporated N-bridge head heteropol cyclic or r fused, metal chelator complexes and/or heterocyclic quinone phytopigment

were conducted covering zero methine, mono methine, meso stibstituted I , trimethine types. I ,
