5-iodoalkyl-4,5-dihydrofurans

& 5-alXylldene-4,5-dihydrofurans 3 and 2,3,5_trisubstituted furans 4 are obtained through a simple sequence, involving, in the Key-step, a regio-and stereoselective iodoenoletherification of P-alXeny1 substituted i,3-dfcarbonyl compounds i.

Dihydrofuran derivatives were obtained by a simple one-step procedure involving an easy epoxidation of 2-alkenyl-1,3-dicarbonyl compounds by dimethyldioxirane prepared in situ and a subsequent cyclisation under the same basic reaction conditions.
