The ketone (±)-5, which embodies the bicyclic core associated with the title tRNA synthetase inhibitors 1 and 2, has been prepared via a three-component coupling reaction involving 2- (hydroxymethyl) cyclopent-2-enone (15), methylamine (6) and propiolamide (10); straightforward elaboration of the readily derived acetates (−)-21 and (+)-21 has provided the biologically active analogues 23 and 24, respectively, of the title compounds.
