CHEMISTRY OF OXALYL DERIVATIVES OF METHYL KETONES. XXV. SYNTHESIS AND CYCLIZATION OF 2-DIAZO-1,5-DIARYL-1,3,5-PENTANETRIONES AND 2-DIAZO-5-ARYL-3,5-DIOXOPENTANOIC ESTERS

2-Diazo-1,5-diaryl-1,3,5-pentanetriones and ethyl 2-diazo-5-aryl-3,5-dioxopentanoates were obtained in the reaction of 5-aryl-2,3-dihydro-2,3-furandiones with aroyldiazomethanes and diazoacetic ester.In some cases the formation of diazopentanetriones is a
