Cycloaddition reaction with the participation of unsaturated ketones catalyzed by an Rh(I)-Sn(II) system

Article abstract of DOI:10.1007/BF00696730

Codimerization of vinyl ketones with metallylacetone or metallylacetophenone in the presence of 2-SnCl2 affords substituted endo-2-acyl-8-oxabicyclo<3.2.1>octanes, the products of the formal <2+2+2> cycloaddition. - Key words: cycloaddition;
