Using sultone chemistry, a short and highly enantioselective synthesis of an advanced precursor for the larger hydroxy acid moiety and of the complete smaller hydroxy acid portion of the macrodiolide antibiotic pamamycin-607 has been accomplished.
Using sultones as crucial intermediates, a short and highly stereoselective synthesis of a precursor of the larger fragment and the methyl ester of the smaller fragment of the macrodiolide pamamycin-607 was achieved.
