Allylation of quinones with allyl (trifluoro)silanes: Direct synthesis of isoprenoid quinones

Hagiwara, Emiko

, p. 2773 - 2776 (1995)

Allylation of a variety of quinones with allyl(trifluoro)silanes takes place with high regioselectivity in the presence of FeCl3·6H2O, giving allylquinones in good yields. This method was used to synthesize biologically active isoprenoid quinones such as plastoquinone-1 and vitamin K1.
