with hydridoaluminates were trapped intramolecularly by esters to provide six- and seven-membered cyclic ketosulfones, exemplified by the stereoselective construction of trans-hydrindanes and of perhydroazulenes. This led to formal syntheses of confertin and damsinic acid.
通过氢化铝铝酸盐处理乙烯基砜形成的阴离子物质被酯类分子内捕获,从而提供六元和七元环状酮砜,例如反式-茚满和过氢azuleneses的立体选择性结构。这导致了铁白蛋白和丹豆酸的正式合成。
