the 3,6-position with a geminal dithiol-bridging group. These sulfur-bridged piperazinediones formally represent derivatives of the 2,4-dithia-6,8-diaza-7,9-dioxobicyclo[3.2.2]nonane ring system. Attempts to transform these sulfur-bridged piperazinediones to 3,6-epidithiopiperazinediones by removal of the bridging group common to the sulfur functionality were unsuccessful. Studies also are reported of
几个反应偕二硫醇与3,6-二溴-1,4-二甲基-2,5-哌嗪二酮在3,6-位被取代的良好的产率哌嗪衍生物,得到偕二硫醇桥接基团。这些硫桥联哌嗪二酮正式代表2,4-二硫-6,8-二氮杂-7,9-二氧代双环[3.2.2]壬烷环系统的衍生物。通过除去硫官能团共有的桥连基团,尝试将这些硫桥连的哌嗪二酮转化为3,6-表二硫代哌嗪二酮是不成功的。还报道了将硫代乙酸加到3,6-二亚甲基-2,5-哌嗪二酮中得到3,6-二乙酰硫基-3,6-二甲基-2,5-哌嗪二酮的研究。将3,6-二乙酰硫基衍生物转化为表硫基哌嗪二酮环系统,得到表二硫代哌嗪和表二硫代哌嗪二酮的混合物。
