Abstract 1'3-Dioxolanes were synthesized by reactions of 3-cyclohexenecarboxaldehyde, 5- norbornene-2-endo-carboxaldehyde with 1, 2-ethanedithiol and 3-(2-propenyloxy)-and 3- propoxy-1, 2-propanediols, aswell as of propionaldehyde, benzaldehyde, and trichloroacetaldehyde with the latter two thiols. Dichlorocarbene addition, bromination, and epoxidation of the ring C= C were accomplished, and activity of the resulting products as ...
