Several approaches have been investigated for the synthesis of a bombesin C-terminal nonapeptide analogue AsnGlnTrpAlaVAlGlyHisLeu-ψCSNHMet-NH2. A new activated dithioester 16 has been synthesized. Thioacylation of methionine methyl ester with 16 was always accompanied by racemization, resulting in the formation of diastereomeric mixtures of reaction products.
几种方法已被研究用于铃蟾肽C-末端九肽类似物AsnGlnTrpAlaVAlGlyHisLeu-ψCSNHMet-NH的合成2。已经合成了新的活化的二硫酯16。甲硫氨酸甲酯与16的硫酰化总是伴随着消旋作用,导致反应产物的非对映异构体混合物的形成。
