The indolealkaloid α-cyclopiazonic acid (CPA) is one of the few known inhibitors of sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) besides the terpenoids thapsigargin and artemisinin. We report here the first asymmetric totalsynthesis of cyclopiazonic acid by a modification of the Knight synthesis, currently the most efficient route to CPA. First structure–activity data of CPA derivatives and stereoisomers
