The totalsynthesis and structural revision of the marine natural product neopeltolide is reported. The key bond-forming step involves a Lewis acid-catalyzed intramolecular cyclization to install the tetrahydropyran ring and the macrocycle simultaneously. This type of cyclization is the first of its kind and assembles the carbon backbone of the natural product efficiently. The synthesis of the reported

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
