Oligomethylene-tethered -alkenyl 3-oxobutanoates and 3-oxobutanamides underwent manganese(III)-mediated oxidative intramolecular addition to produce dihydrofuran-fused macrolides and macrocyclic amides from 8 to 26 members. A similar reaction of the oligooxamethylene-tethered -alkenyl 3-oxobutanoates also gave dihydrofuran-fused crown ether type macrolides which had a phase-transfer ability with sodium and potassium picrates. The manganese(III)-assisted specific intramolecular addition could be explained by the -complexation of the -alkenyl part with the manganese(III) enolate. Georg Thieme Verlag Stuttgart - New York.
