Synthetic Studies toward Australifungin

Abstract

AbstractAs a fungal metabolite, australifungin possesses an α-diketone and a β-ketoaldehyde moiety on its trans-decalin backbone. Microwave-assisted intramolecular Diels–Alder reaction was used as a key strategy to establish the trans-decalin moiety. Further functionalization of the ring B side chain installed the β-ketoaldehyde, one of the two unique functional groups along with the α-diketone.
