Syntheses of the hexahydroindene cores of indanomycin and stawamycin by combinations of iridium-catalyzed asymmetric allylic alkylations and intramolecular diels-alder reactions

Short and concise syntheses of the hexahydroindene cores of the antibiotics indanomycin (X-14547 A) and stawamycin are presented. Key methods used are an asymmetric iridium-catalyzed allylic alkylation, a modified Julia olefination, a Suzuki-Miyaura coupling, and an intramolecular Diels-Alder reaction.

Total Synthesis of Ionophore Antibiotic X-14547A

A highly stereocontrolled and convergent total synthesis of optically active ionophore antibiotic X-14547A (1) was designed and carried out.Degradative reactions led to the key intermediates 3 and 6, which served as convenient comparison stages.The tetrah
