3,9-Diethylidene-2,4,8,10-tetraoxaspiro[5.5]undecane (DETOSU) is a bicyclic ketene acetal derived from the isomeric allyl acetal 3,9-divinyl-2,4,8,10-tetraoxaspiro[5.5]undecane (DVTOSU). As a bifunctional monomer, DETOSU is an important building block for polyorthoesters formed by the addition of diols to the activated double bond of the diketene acetal.
