• study the CO2 capture, but the need of high energy to regenerate the amine solutions after CO2 capture, hinders their applications further [2]. In the domain of porous materials, zeolites, metal-organic frameworks (MOFs), cage molecules, etc. have been introduced for selective uptake of CO2 [3][4][5

• architecturally intricate cage molecules is a worthwhile challenge. The unique properties associated with the carbocyclic cage frameworks are the main reasons for pursuing their synthesis [1][2]. They are valuable synthons to assemble natural as well as non-natural products [3][4]. In addition, the cage molecules

In view of various applications of cage molecules and the documented difficulties in their synthesis, we conceived a short synthetic route to C2-symmetric bis-spiro-pyrano cage compound 7. To this end, the Grignard addition and ring
