CHEMISTRY OF OXALYL DERIVATIVES OF METHYL KETONES. XXIII. REACTION OF 5-ARYL-2,3-DIHYDROFURAN-2,3-DIONES WITH ALDEHYDES AND KETONES

Andreichikov, Yu. S.,Gein, L. F.,Plakhina, G. D.

, p. 1995 - 1998 (2007/10/02)

5-Aryl-2,3-dihydrofuran-2,3-diones react with aldehydes, ketones, and α-ketoesters to form 2,2,5,6-tetrasubstituted 1,3-dioxen-4-ones.The reaction of 5-aryl-2,3-dihydrofuran-2,3-diones with α-diketones occurs either at one carbonyl group of the α-ketone to form 2,6-disubstituted 1,3-dioxen-4-ones or at both carbonyl groups to form 2,2',6,6'-tetrasubstituted 4,4'-dioxo-2,2'-bi(1,3-dioxenyls).
