incorporated into cyclic peptide analogues of the ring C of lantibiotic nisin, we report here the stereoselective synthesis of the new (S,R)- and (R,R)-alpha-methylnorlanthionines (alpha-Me-nor-Lan). The orthogonally protected derivatives of these compounds have also been prepared. The key step in the synthesis of these bisamino acids was the S(N)2 opening reaction of the corresponding cyclic sulfamidates
[反应:请参阅文本]由于以前已经将不常见的氨基酸降冰硫氨酸(nor-Lan)掺入羊毛硫菌素乳链菌肽C环的环状肽类似物中,因此我们在此报告了新(S,R)-和( R,R)-α-甲基降冰片氨酸(α-Me-nor-Lan)。还制备了这些化合物的正交保护的衍生物。合成这些双氨基酸的关键步骤是相应的环状氨基磺酸盐与带有适当保护的1-半胱氨酸衍生物的SH基团的S(N)2开环反应。
