The aforementioned authors prepared lactone 6 for the first time but the Experimental Section of their study details no more than a 2% yield of 6 separated chromatographically from a 54%:8%:3%:2%:trace mixture of five compounds; accordingly, 6 becomes a synthetically useful reagent only on the grounds of our two-step synthesis (Scheme 5).

A referee suggested that "the possibility of directly obtaining xerulinic acid from xerulin should be commented on". We are unaware of such a possibility; furthermore, during alternative attempts at the synthesis of xerulinic acid, we prepared both the corresponding alcohol (" xerulinol") and aldehyde ("xerulinal") but could not oxidize either to xerulinic acid: K. Siegel, Ph.D. Thesis, Universität Freiburg, 2000.
