Total synthesis of (+)-calyculin A and (-)-calyculin B: Asymmetric synthesis of the C(9-25) spiroketal dipropionate subunit

An asymmetric synthesis of the stereochemically fully endowed C(9-25) spiroketal fragment (+)-BC of the calyculins (1-8) is described. Highlights of the synthesis include: a highly diastereoselective IBr-induced iodocarbonate cyclization to introduce the
