摘要
A key step in the synthesis of the C1-C9 fragment of the ionophore antibiotic ionomycin involves the addition of an alkylcopper(I) reagent to an ester-functionalised cationic eta(3)-allylicmolybdenum and an alkylzinc cuprate to the corresponding eta(3)-allyliciron complex. The reaction is regioselective and the metal directs enantiofacial attack (anti). The stereochemistry of the reactions is proven by an independent synthesis.
