the first total syntheses of several members of this family, including sceptrin, ageliferin, nagelamide E, nakamuric acid (and its methyl ester), and oxysceptrin. Details on the fascinating conversion of sceptrin to ageliferin, which has been used to produce gram quantities of this sensitive natural product, are provided. In addition, the first enantioselectivetotalsynthesis of sceptrin and ageliferin
