SINTEZA I FOTOKEMIJSKA SVOJSTVA 2, 3-DIVINILBENZO[b]FURANSKIH DERIVATA
The conjugated hexatriene systems with a central double bond placed in a furan ring (1a-d) have been thoroughly investigated [1]. They behave completely different from the hexatriene system with the central double bond incorporated in benzene ring (2) [2] under the same reaction conditions. Compared to diheteroaryl systems (2), in which the intramolecular cycloaddition and cis-trans isomerization were the competitive processes, the 2, 3-divinylfuran derivatives (1a-d) undergo only cis-trans isomerization to trans, trans-isomers. The dienic character of the furan ring and prevailing conformation of the furan double bonds causes the [2+2] cycloaddition within the furan ring followed by rearrangement, rather then the intramolecular [2+2] cycloaddition of ethylenic bonds. In this work the hexatriene system with the central double placed in an annelated furan ring (3a-e) is studied. Herewith the [2+2] cycloaddition within the furan ring followed by rearrangement of 2, 3-divinylbenzo[b]furan derivatives (3a-e) is not expected but the [2+2] cycloaddition of ethylenic bonds might be the reaction course. The photochemical behaviour of these novel compounds will be presented
