✦ Synopsis

The naturally occurruq enantlomer of peatalenolactone E was synthesized as Its levorotatory Me ester 1 starting from (+)-2-ethoxycarbonyl-7,7-ethylenedioxyblcyclo[3.3.0loctan-3-one 3, which was obtarrxl by treatng (?)-3 with baker's yeast. The absolute configuration of pentalenolactone E Me ester was established as depicted In 1.
