L-isomer is easily converted to the vinyl lactone 1 via three convenient reactions in an overall 69% yield. Reaction of the D isomer of 1 with a variety of carbon, oxygen, sulfur, and nitrogen nucleophiles and a palladium catalyst produced carboxylic acids that were esterified with methyl iodide to give the esters 2. Alternatively, reaction of L-lactone 1 with Ph 3 P=CHCO 2 Et provided the Wittig product
