complex marinenaturalproduct, (+)-discodermolide (1), using a hybridized Novartis−Smith−Paterson synthetic route is presented. This contribution, which is the concluding part of a five-part series, highlights a reagent-controlled stereoselective boron enolate aldol reaction between 2 and 3 forming the C7 hydroxyl-bearing stereocenter, selective reduction of 4a to generate the 1,3-anti-diol 5, and a
