Ikarugamycin : Total Synthesis of the Decahydro-as-indacene Portion

An efficient , stereoselective synthesis of octahydro-as-indacenone 2 , the carbocycle fragment of the antibiotic ikarugamycin , is described.The prominent step in the sequence is an intramolecular Diels-Alder reaction, which establishes the relative stereochemistry of 2.
