Stereospecific synthesis of Conduramine-F4 and Conduritol-F has been achieved by fully stereospecific cyloaddition of singlet oxygen to cyclohexadiene ketal 1 followed by reductive extrusion of one oxygen atom. The obtained monoepoxide 3 has been smoothly opened to conduritol-F4 and conduramine-F4 6 by water and ammonia, respectively.
