6-(2,4-Dioxopentyl)-2,2-trimethyl-4H-1,3-dioxin-4-one on reflux in toluene gave MeCOCH2COCH2 COCH=C=O, which cyclized to 6-(2-oxopropyl)-4-hydroxy-2H-pyrin-2-one or was trapped with alcohols to produce resorcylate esters. The method was used for the synthesis of both enantiomers of montagnetol and erythrin. (c) 2009 Elsevier Ltd. All rights reserved.
