Five-steps conversion of 3,6-dialkyl-1,4-dimethyl-2,5-piperazinediones into the corresponding 3,6-epithio and -epidithio derivatives: i.e. conversion into 3,3α,6,6α-tetrabromide, substitution of 3,6-bromine atoms with methanol, reduction of 3α,6α-bromine atoms, conversion of 3,6-methoxyl groups into mercapto groups, and then oxidation, is described.
