title: The total synthesis of (±)-fumimycin.
abstract: The antibiotic agent fumimycin has been synthesized for the first time. This natural product was found to inhibit the bacterial peptide deformylase and may represent a lead structure to a class of novel antibacterials. Our synthetic strategy towards fumimycin involved the following steps: Dakin oxidation of an aldehyde functionality, conversion of an oxime through radical fragmentation to form an N-diphenylphosphoryl group, construction of an α-trisubstituted amine by 1,2-addition to a ketimine, a Claisen rearrangement with subsequent transition-metal-catalyzed olefin isomerization to install a propenyl chain and final amidation.
