Popis: We report synthesis of two diastereomeric structures previously proposed for the complex secondary metabolite pseurotin A(2). Both structures were accessed from the same building blocks taking advantage of a stereodivergent nickel(II)-iamine-catalyzed 1,4-addition of a chiral 2-alkoxycarbonyl-3(2H)-furanone. Late-stage Csp-Csp(3) cross-coupling of a highly functionalized bromoalkyne featured in the pseurotin A(2) side-chain assembly. The work supports the 2016 stereochemical revision of pseurotin A(2) and represents the first chemical synthesis of this natural product.
