Total synthesis of 11-alpha-methoxycurvularin and 11-beta-methoxycurvularin has been accomplished in a highly stereoselective manner by utilizing Jacobsen hydrolytic kinetic resolution, Maruoka asymmetric allylation and intramolecular Friedel-Crafts acylation as key steps.

A simple and highly efficient stereoselectivetotalsynthesis of (11β)‐11‐methoxycurvularin (5), a polyketide natural product, was achieved. The synthesis commenced with a Cu‐mediated regioselective opening of (2S)‐2‐methyloxirane (6) and comprised a Keck asymmetric allylation and intramolecular Friedel–Crafts acylation as key steps (Scheme 2).
