Popis:	An improved procedure for the synthesis of diastereo-enriched tetrasubstituted 4,5-dihydrofurans by using I2-induced enolcyclization of B-keto esters is reported. The reactions using 12 in anhydrous MeCN are considered under thermodynamic control and the more stable trans isomers are preferentially produced.
