Direct lithiation of β-ethylthio- and β-phenylthioacrylic acid affords β-lithiopropionate equivalents.The usefulness of these reagents is demonstrated in a convenient synthesis of α,β-unsaturated δ-lactones and their transformation into the corresponding saturated δ-lactones.The required reaction with epoxides as electrophiles was promoted by addition of boron trifluoride-ether.
