Synthesis of new furan polycycles via photochemical reaction in neutral and acidic medium
New furan derivatives of o-divinylbenzenes were synthesized and their photochemical reactivity has been investigated in neutral and acidic medium. Depending of the structure of the starting materials and pH value, the new cyclization (11, 16, 20), cycloaddiotion (12, 13, endo-17, exo-18), electrocyclization (21, 22) and dimeric (15, 19) products were isolated. While photochemical investigation in neutral medium showed that the main intramolecular process is cycloaddition, in the case of acidic photochemistry, due to the protonation of the starting molecule, electrocyclization process comes to expression and formation of dihydronaphtalene products 21 and 22.
