The protected pentapeptide formyl-L-leucyl-Nγ-benzyloxycarbonyl-L-α,γ-diaminobutyryl-Nγ-benzyloxycarbonyl-L-α,γ-diaminobutyryl-L-threonyl-Nγ-benzyloxycarbonyl-L-α,γ-diaminobutyric acid, a sequence which is known to occur in the polymyxins, has been synthesized. Different coupling methods including the azide route lead to the same end product, with the same optical rotation. We therefore believe our
被保护的五肽甲酰基-L-亮氨酰基-N γ -苄氧羰基-L-α,γ二氨-N γ -苄氧羰基-L-α,γ二氨-L-苏-N γ -苄氧羰基-L-α,γ-已经合成了已知在多粘菌素中存在的序列二氨基丁酸。包括叠氮化物路线在内的不同耦合方法导致相同的最终产品具有相同的旋光度。因此,我们认为我们的五肽是光学纯的。
