The total synthesis and biologicalevaluation of neopeltolide and analogs are reported. The key bond-forming step utilizes a Lewis acid-catalyzed intramolecular macrocyclization that installs the tetrahydropyran ring and macrocycle simultaneously. Independent of each other, neither the macrolide nor the oxazole sidechain substituents of neopeltolide can inhibit the growth of cancer cell lines. The
