The development of high-performance recyclable polymers represents a circular plastics economy to address the urgent issues of plastic sustainability. Herein, we design a series of biobased seven-membered-ring esters containing aromatic and aliphatic moie

3-Vinylbenzofuran, 3-isopropenylbenzofuran and 2-methyl-3-vinylbenzofuran give normal adducts with ethenetetracarbonitrile, accompanied, in the case of the last named diene, by the isomeric cyclobutane.Normal adducts also result from these dienes and 4-phenyl-1,2,4-triazoline-3,5-dione, and from 3-vinylbenzofuran and both maleic anhydride and N-phenylmaleimide. 3-Vinylbenzofuran gives the rearranged adduct dimethyl 1,2-dihydrodibenzofuran-3,4-dicarboxylate with dimethyl acetylenedicarboxylate.

Photocyclization reactions were carried out on ethyl 2-formylphenoxyacetates 1a-e and ethyl 2-acetylphenoxyacetates 2a-e in acetonitrile.Irradiation of 1a-e gave dihydrobenzofuranols 3 in 20-46percent yields.Similarly, irradiation of 2a-e afforded dihydrobenzofuranols 6 and their derivatives 7, 8 in 40-86percent yields.Substitution effects on photocyclization and reaction pathways are discussed.
