• Reaction of 3,6-diethoxycarbonyl-1,4-dimethyl-2,5-piperazinedione (15), prepared by heating of diethyl methylaminomalonate (14), with NaH in dioxane and followed treatment with S_2Cl_2 gave 3,6-epidithio- and 3,6-epitetrathio-3,6-diethoxycarbonyl-1,4-dimethyl-2,5-piperazinediones (16b and 16d), which have the skeletone (1) observed in fungal metabolites such as sporidesmin. The reduction of 16 with NaBH_4 in methanol gave the dethio derivative (15) in good yield. The reaction of 16d with triphenylphosphine in tetrahydrofurane gave 16c and 16b. The reaction of diethyl malonate derivatives (23a, b, and c) with NaH and S_2Cl_2 in dioxane gave the corresponding disulfides or trisulfides (24a, b, and c). Some reactions of proline anhydride (5) and sarcosine anhydride (7) with S_2Cl_2 or sulfur were examined.
