Abstract

AbstractThe first total synthesis of the chlorinated resorcylic acid lactone cochliomycin C is achieved starting from the readily available sugar D‐lyxose. The strategy has also lead to the total synthesis of natural resorcylic acid lactones paecilomycin E, paecilomycin F and a synthetic analogue 6‐epi‐cochliomycin C. The key reactions include Ohira–Bestmann alkynylation, ring closing metathesis and regioselective methylation under Mitsunobu conditions.
