The antifungal polyketides alatanones A and B and trineurones A–E have been synthesized using a one-pot C-acylation reaction coupling 1,3-cyclohexanediones with the appropriate carboxylic acids. This key transformation is believed to proceed via initial carbodiimide-mediated O-acylation followed by a DMAP-catalyzed Claisen–Haase rearrangement, resulting in O to C acyl migration.
