• Dimerization of 16,17-dehydrodigitoxigenin 3-acetate (I) and its 21R-and 21S-ethoxy derivatives (II and III) was found to occur on heating the monomers in toluene. This dimerization appeared to take place between the 16,20 (22)-diene system of one monomer and the 16,17-double bond of another monomer by a Diels-Alder type reaction, giving the dimers IV, V, and VI, respectively. Ultraviolet irradiation of a chloroform solution of II also gave the dimer V, but UV irradiation of I and III was ineffective. The structures of these dimers were established on the basis of their molecular weights, spectral data, and the properties of their dianhydro derivatives.
