Abstract: The title bicyclic lactone, C₁₉H₁₉NO₃, is an intermediate in the synthesis of chiral -methylprolines and branched C-methyl pyrrolidines; the absolute configuration was determined by the use of D-erythronolactone as the starting material. It exhibits no unusual crystal packing features, and each molecule acts as a donor and acceptor for one C-HO hydrogen bond.
