An approach to the macrocycliccore of phomactin A is described. Central to this strategy is the use of a cis-fused oxadecalin intermediate, prepared using the dihydropyrone Diels-Alder reaction. The conformational bias inherent to this system is then used to facilitate macrocycle formation via an intramolecular B-alkyl Suzuki coupling.

The reaction of europium(III) or terbium(III) chlorides with ethyl 2-hydroxymethylidene-3-oxobutanoate in the presence of 2,2'-bipyridine (2,2'-bipy) resulted in the luminescent complexes [LnL(3)]center dot 2,2'-bipy (L = ethyl 2-hydroxymethylidene-3-oxobutanoate, Ln = Tb-III or Eu-III), whose molecular structure has been determined by X-ray analysis.
