α-Conidendrin as a Source for Preparation of Sikkimotoxin Derivatives
摘要:
Oxidation of a-conidendrin (3) by Fremy's salt favored formation of an o-quinone (4) at the pendant aromatic ring as opposed to the fused aromatic ring. Quinone reduction and phenolic methylation, followed by lactone reduction, and subsequent oxidation by dichlorodicyanoquinone produced sikkimotoxin oxabicyclooctane (7), while oxidation with cupric sulfate/potassium persulfate gave sikkimotoxin dioxatricyclodecane (8).
