The syntheses of acromelic acid A 1, allo-acromelic acid A 19 and an approach towards acromelic acid B 2 are described. Palladium (0) catalysed cross-coupling reactions were used to generate C-4 catechol precursors and formation of the pyridone rings was investigated using a biomimetic oxidative cleavage - recyclisation strategy.
