Stereoselective synthesis of (+)-goniodiol, (+)-goniotriol, (-)-goniofupyrone, and (+)-altholactone using a catalytic asymmetric hetero-Diels-Alder/allylboration approach

The stereoselective total synthesis of several members of the styryllactone family was achieved efficiently from common intermediate 8, prepared by a catalytic asymmetric inverse-electron-demand hetero-Diels-Alder/allylboration sequence. The transformatio

A concise synthesis of (+)-goniodiol using a catalytic hetero Diels-Alder/allylboration sequence

A new short and efficient synthesis of (+)-goniodiol is reported using a catalytic asymmetric hetero Diels-Alder/allylboration sequence. Georg Thieme Verlag Stuttgart.

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.
