The chalcone derivatives of spirochromanoid frame have been synthesized starting from resorcinol. It is converted in to the spirochomanone protected by N-Boc-4-piperidone. The chalcones of this spirochromanone are synthesized by Claisen Schmidt condensation reacting with 2-chloro benzaldehyde, 2-fluro benzaldehyde, 4-methoxy benzaldehyde, 2,4-dimethoxy benzaldehyde, Benzo-1,3-dioxole-5-carbaldehyde. They are further characterized by their IR, NMR, C13, Depth analysis.
