Özet

Radical cyclization reactions of both aliphatic 1,3-diones 1a and 1b and of cyclic 1,3-diones 1c-1c with 2-thienyl- and 3-thienyl-substituted alkenes 2a-2d in the presence of manganese(III) acetate were investigated. Thienyl-substituted dihydrofurans 3 were obtained with moderate to high yields ( Table 1 -3). Also, the favorable effect of the thienyl substituent on the intermediate carbocation stability was evaluated by comparison with a phenyl substituent. © 2013 Verlag Helvetica Chimica Acta AG Zürich.
