Ready available 3-phenylselanylfuran-2(5H)-one undergoes tandem conjugate addition-alkylation by organocopper reagents to afford, with good yields and diastereoselectivities, 3,4-disubstituted-3-phenylselanyl-γ- butyrolactones, which can be transformed into naturally occurring compounds, such as lignans.

An efficient protocol for stereo- and regiocontrolled synthesis of small polyfunctional molecules is presented. The stereospecific addition of PhSeCl to 2,5-dihydro-2,5-dimethoxy-furan 1 in solvents, such as methylene chloride and methanol, gives cyclic and linear acetals 2 and 3, depending on the solvent used. Emphasis is given to the regiocontrolled hydrolysis of acetal groups for the preparation of stereodefined and highly functionalized C4 synthons, such as 8, 9 and 13.
