Abstract
Direct lithiation of ß-phenylthioacrylic acid and of methyl propiolate affords useful ß-lithioacrylate and ß-lithiopropionate equivalents. This is demonstrated in this paper in a convenient synthesis of (±)-eldanolide (±)-1 and in the transformation of butenolide (±)-7 into butyrolactone (±)-9, respectively.Keywords
