synthesis of spiroketal natural product (+)-aculeatin D and unnatural (+)-6-epi-aculeatin D has been accomplished. Sharpless kinetic resolution of secondary allylic alcohol and phenyliodine(III) bis(trifluoroacetate) (PIFA)-mediated oxidative spirocyclization were used as key steps in this synthesis.
