Abstract

The total synthesis of auripyrones was achieved by using a novel aldol-type reaction of γ-pyrone as a key step. From this synthetic work, we have established the stereostructure and absolute configuration of auripyrone B. Furthermore, the cytotoxicities of auripyrones against a panel of 39 human cancer cell lines (termed JFCR39) at the Japanese Foundation for Cancer Research were investigated. The patterns of the differential cytotoxicities of auripyrones were COMPARE negative, suggesting that they inhibit cancer cell proliferation through a novel mechanism.
