摘要：

A permethylated analogue 1 of the mushroom pigment norbadione A was synthesized through a double Suzuki-Miyaura coupling of 1,7-diboronated naphthalene 2 and triflate 3. ESI-MS studies showed similar constants for the formation of the complexes of the norbadione A dipotassium salt and of 1 with a cesium ion, thus suggesting that cesium complexation involves the two pulvinic acid parts of these molecules. Tf = trifluoromethanesulfonyl.
