A ring-opening [3+2] annulation reaction between cyclopropenones and amides was developed to produce 5-amino-2-furanones. Insertion of the carbonyl group of an amide to the C-C single bond of a cyclopropenone occurred efficiently in the presence of a catalytic amount of silver(i) triflate.

The carbonylation of diphenylacetylene (1a) in ethanol in the presence of Rh4(CO)12/Na2CO3 as a catalyst gave 5-ethoxy-3,4-diphenyl-2(5H)-furanone (3b) in a 72percent yield, together with 3-(ethoxycarbonyl)-2-phenylindanone (11percent) and diethyl 2,3-dip

Rhodium carbonyl-catalyzed reactions of internal acetylenes with ethylene and CO in protic solvents, e.g., ethanol, gave 3,4-disubstituted-5-ethyl-2(5H)-furanones in good yields.By using propylene or methyl acrylate instead of ethylene, small amounts of 5-n-/isopropyl-2(5)H-furanones or 5--2(5H)-furanone were obtained.

, p. 993 - 996 (2007/10/02)
Reactions of internal acetylenes with CO in alcohols gave 5-alkoxy-3,4-disubstituted-2(5H)-furanones in good yields in the presence of rhodium catalysts containing basic alkali metal salts, e.g., Rh4(CO)12 or RhCl2*3H2O in combination with sodium carbonat
