چکیده انگلیسی
α-d-xylo-7,3-Unsaturated lactone, a versatile chiral building block, undergoes Cu-catalyzed conjugated addition with high yield and stereoselectivity. When the conjugated reaction is quenched with a suitable alkyl halide, a tandem stereoselective conjugated/α-alkylation reaction is achieved. Further, selective hydrolysis of the 1,2-O-isopropylidene moiety followed by oxidative cleavage and reduction reaction, afforded the title compounds.
