Abstract

Procédé de préparation de delta -oxoacétals beta , gamma -éthyléniques consistant à faire réagir en présence d'un acide de Lewis un orthoester d'un alcanol avec un diéne-1,3 oxysilane dérivé d'un aldéhyde ou d'une cétone alpha , beta - ou beta , gamma -éthylénique énolisable. Les delta -oxoacétals éthyléniques peuvent être utilisés notamment pour la préparation de composés delta -dicarbonylés et en particulier de delta -dialdéhydes.
