the synthesis of beta-amino disulfides by regioselective ring opening of sulfamidates with benzyltriethylammonium tetrathiomolybdate [BnNEt3](2)MoS4. Stability and reactivity of different protecting groups under the reaction conditions have been discussed. This methodology has also been extended to serine and threonine derived sulfamidates to furnish cystine and 3,3'-dimethyl cystine derivatives.
在此,我们报告了一种简单有效的方法,用于通过磺酰胺与四硫代钼酸苄基三乙基铵 [BnNEt3](2)MoS4 的区域选择性开环来合成 β-氨基二硫化物。讨论了不同保护基在反应条件下的稳定性和反应性。这种方法也已扩展到丝氨酸和苏氨酸衍生的磺酰胺以提供胱氨酸和 3,3'-二甲基胱氨酸衍生物。
