Silver catalyzed decarbonylative [3 + 2] cycloaddition of cyclobutenediones and formamides

As an important moiety in natural products, N,O-acetal has attracted wide attention in the past few years. An efficient method to construct N,O-acetal has been developed. Using silver catalyst, cyclobutenediones were smoothly converted to the corresponding γ-aminobutenolides in the presence of formamides, in which cyclobutenediones likely proceed with a key decarbonylative [3 + 2] cycloaddition process. In this way, a series of products with varied substituents were isolated in moderate yield and fully characterized.

Reactions of carbonyl compounds in basic solutions. Part 25. 1 the mechanism of the base-catalysed ring fission of 3,4-diphenylcyclobut-3-ene-1,2-diones

The rate coefficients for the base-catalysed ring fission of a series of substituted 3,4-diphenylcyclobut-3-ene-1,2-diones to give the corresponding (Z)-2-oxo-3,4-diphenylbut-3-enoic acids have been determined in 50% (v/v) aqueous dimethyl sulfoxide (DMSO
