A stereoselectivesynthesis of the macrolactonecore of the potent anticancer agent neopeltolide is disclosed. The key steps of the synthesis include asymmetric allylation using Krische’ protocol, conjugate reduction using MacMillan’s methodology, and an asymmetric hetero-Diels–Alder reaction using Jacobsen’s catalyst. Substrate controlled diastereoselective 1,3-anti reduction of a keto alcohol, Luche
