An effective extension of the polyacetate chain in the polyene macrolide antibiotic filipin III, based on chiral oxazaborolidinone-promoted asymmetric aldol reactions

The enantioselective construction of the iterative polyacetate unit 3 in filipin III has been accomplished, essentially by an aldol strategy based on chiral oxazaborolidinone-promoted asymmetric aldol reactions. (C) 2000 Elsevier Science Ltd.
