Cyclopropenone has emerged as a highly versatile precursor in organic synthesis due to its diverse reactivity. The cyclopropenone derivatives could undergo various transformations such cycloaddition reactions, ring-opening and isomerization reactions the presence of different chemical reagents. Over years, significant progress been made manipulation cyclopropenones for construction carbocycles, heterocycles, other useful compounds. Despite several reviews that have concerned chemistry cyclopropenones, utility motifs carbocycles heterocycles rarely reported. Herein, we report recent advancements synthetic precursors towards compounds with biological significance.
