A stereoselective synthesis of (−)-1-epi-ventiloquinone L and (+)-ventiloquinone L, the monomeric unit of cardinalin 3 has been described. The synthesis is completed in 7 steps with 10.5% and 13% overall yields for (−)-1-epi-ventiloquinone L and (+)-ventiloquinone L respectively. The key steps involve Dötzbenzannulation of carbene 5 with alkyne 6 to give a substituted naphthalene moiety and oxa-Pictet–Spengler
