The asymmetric synthesis of (1S,3R,5R,7S)-(+)-sordidin and 7-epi-(1S,3R,5R,7R)-(–)-sordidin, both components of the natural male-produced aggregationpheromone of the banana weevil Cosmopolites sordidus (Germar), starting from 2,2-dimethyl-1,3-dioxan-5-one is described. Two of the stereogenic centers were generated by three α-alkylations of the corresponding RAMP-hydrazone. Diastereoselective epoxide
