What is it about?
Heterocycle-Heterocycle Synthetic Strategies (HHSS) [Heterocyclic transformation ]was based on different types of reactions eg cycloaddition, cyclo condensation, molecular rearrangement, ANRORC. Spiro condensed noncondensed, heterocycles were obtained via HHSS from easy one-pot reactions in moderate to high yields.

Why is it important?
it is a one-pot reaction for the synthesis of target heterocycles [Cyclimides, fused oxazines, fused pyrimidines, fused pyridazines, fused pyrans, fused thiopyrans] from the following useful building blocks, namely 1,3-oxazoles, uracils, 2,3-oxazines, pyridazines, 2,3-benzoxazines, quinazolines, pyridopyridazines, benzopyranes,benzothiopyranes, and spirooxiranes , in different synthetic pathways
Perspectives
Heterocycles as building blocks is a good strategy for easy access to different target heterocyclic systems.
