Stereoselective synthesis of optically active perhydrofuro[2,3-b]furan derivatives

Abstract (1 R ,5 S )-2,8-Dioxabicyclo[3.3.0]octan-3-one and its derivatives, important subunits in various biologically active natural products, have been synthesized based on a new approach using the asymmetric oxyselenenylation of 2,3-dihydrofuran as the key step.
