[GRAPHICS]During our efforts to synthesize the cytotoxic natural product FR182877, we discovered intramolecular reductive acylations that offer a stereocontrolled alternative to the classical Knoevenagel condensation for the formation of alpha -alkylidene beta -keto-delta -lactones. Other progress toward a synthesis of FR182877 includes a pi -allyl Stille coupling and a bromo Horner-Wadsworth-Emmons reaction that forms a 12-membered ring. Structural relationships among FR182877, hexacyclinic acid, macquarimicin A, and cochleamycin A are also discussed.
