dual-catalytic strategy for the radical decarboxylation functionalization of aliphatic carboxylic acids. The photoinduced ligand-to-iron charge transfer process under light was initially occurred to generate an unstabilized alkyl radical, and the copper catalyst delivered the radical and enabled the subsequent coupling reactions to form C–N or C–C bonds. By merging iron-catalyzed decarboxylation with copper catalysis

higher ergosterol preference than AmB itself. Monte Carlo conformational analysis of 2-4 based on NOE-derived distances indicated that the amino-sugar moiety of 2 comes close to C41 because of the short bridge, whereas those of 3 and 4 are pointing outward. The mutual orientation of the amino-sugar moiety and macrolide ring is so rigid in derivatives 2 and 3 that these conformations should be unchanged
