                                    A straightforward approach to 4-pyrone-containing natural products has been developed, which includes an aldol-type reaction between 2,6-diethyl-3,5-dimethyl-4-pyrone and aldehydes. The counter cation of the carbanion of the pyrone was found to play an important role in this reaction.
