Palladium catalyzed carbonylative cross-coupling of 4-chloro-2,3-disubstituted-2-cyclobutenones with alkenyl-, aryl-, and heteroaryltin reagents and thermolysis provides a general method for the synthesis of 2,3,6-trisubstituted-2-pyrones. The reaction is
Practical Organic Synthesis with Strained-Ring Molecules. Rhodium-Catalyzed Carbonylation of Cyclopropenyl Esters and Cyclopropenyl Ketones to α-Pyrones and of Vinyl Cyclopropenes to Phenols
Cho, Suk H.,Liebeskind, Lanny S.

Cyclopropenyl esters, prepared from alkynes and ethyl diazoacetate via rhodium acetate catalysis, can be converted into cyclopropenyl ketones, which in turn are converted into vinyl cyclopropenes.All three classes of cyclopropenes undergo rhodium-catalyze
