Stereocontrolled Synthesis of Calyculin A: Construction of the C(15)-C(25) Spiroketal Unit

Two concise enantioselective syntheses of the C(15)-C(25) spiroketal unit of calyculin A, using derivatives of allyldiisopinocampheylborane efficiently to control 1,2- and 1,3-diol stereochemistries, are reported.
