Stereoselective Syntheses of (+)-Goniotriol, (+)-8-Acetylgoniotriol, (+)-Goniodiol, (+)-9-Deoxygoniopypyrone, (+)-Altholactone, and (-)-Goniofupyrone

The γ-lactone intermediate (-)-7, derived from (+)-tricarbonyl(η6-o-(trimethylsilyl)benzaldehyde)chromium(0) complex, was efficiently converted into the corresponding δ-lactone intermediate (-)-11. This second intermediate has been shown to be a versatile compound for stereoselective syntheses of natural styryllactones possessing a six-membered lactone moiety, isolated from Goniothalamus giganteus, by transforming it into (+)-goniotriol, (+)-8-acetylgoniotriol, (+)-goniodiol, (+)-9-deoxygoniopypyrone, (+)-altholactone, and (-)-goniofupyrone.

Studies on total syntheses of antitumor styryllactones: Stereoselective total syntheses of (+)-goniofufurone, (+)-goniobutenolide A, and (-)-goniobutenolide B

A highly stereoselective aldol reaction of the aldehyde 11, derived from (+)-tricarbonyl(η6-2-trimethylsilylbenzaldehyde)chromium(0) complex (4), with 2-trimethylsilyloxyfuran afforded the γ-lactone derivative 13. The γ-lactone 13 was subsequently converted into three antitumor styryllactones, (+)-goniofufurone, (+)-goniobutenolide A, and (-)-goniobutenolide B.

An optically active chromium(0)-complexed benzaldehyde derivative in organic synthesis: A highly stereocontrolled total synthesis of (+)-goniofufurone

An antitumor styryl-lactone, (+)-goniofufurone was synthesized in a highly diastereoselecdve manner from (+)-tricarbonyl(η6-2-trimethylsilylbenzaldehyde)chromium(0) complex through stereoselective aldol reactions as crucial steps.
