结果(±)-粘球蛋白的合成。如方案I所述,1,4-二甲基-2,5-哌嗪二酮(2,肌氨酸酐)与甲酸乙酯和甲醇钠的单甲酰化得到烯醇醛3,产率96%.烯醇3可以在低温下在碱存在下与各种次磺酰氯干净地磺酰化,
Results Synthesis of (±)-Gliovictin. As outlined in Scheme I, monoformylationof 1, 4-dimethyl-2, 5-piperazinedione (2, sarcosine anhydride) with ethyl formate and sodium methoxide provides enolic aldehyde 3 in 96% yield. Enol 3 can be sulfenylated cleanly at low temperature with a variety of sulfenylchlorides in the presence of base, 3
