The totalsynthesis of aculeatins A and B is described proving the versatility of Prinscyclization in natural product synthesis. The approach is convergent and highly stereoselective. Morpholine amide coupling with an alkyne and PIFA-mediated oxidative spirocyclization were utilized as key steps. aculeatins - Prinscyclization - morpholine amide - PIFA-mediated oxidative spirocyclization

moiety with appropriate configuration was accomplished from the commercially available L‐malic acid. The key steps in this synthesis are the Barbier allylation, LiAlH4/LiI‐mediated syn‐stereoselective 1,3‐asymmetric reduction, and phenyliodine bis(trifluoroacetate) (=[bis(trifluoroacetoxy)iodo]benzene; PIFA) mediated oxidative spirocyclization.
