STRUCTURAL MODIFICATION OF 11-ISOPROPYLIDENE endo-TRICYCLO[6.2.1.02,7]UNDECA-4,9-DIENE-3,6-DIONE TO IMPROVE THE STABILITY
摘要:
Selective epoxidation of 11-ene double bond in 11-isopropylidene-endo-tricyclo[6.2.1.02.7]undeca-4,9-diene-3.6-dione (1a) by mCPBA afforded exclusively syn-epoxide 3,3 is much more stable than 1a. Photocycloaddition of 3 resulted the corresponding trishomocubane 4. Single crystal X-ray analysis of 4 was carried out to establish the stereochemistry of the epoxide moiety.
