serine protease (alpha-chymotrypsin or subtilisin BPN') and Aspergillus genus aminoacylase on racemic N-acetyl-alpha-aminoalkanedioic acid alpha,omega-diester produced L-alpha-aminoalkanedioic acid omega-ester in good yield and high optical purity. L-alpha-Aminosuberic acid omega-ester thus obtained was conveniently introduced into an oxytocin analog, [Asu1,6]oxytocin, by the solid-phase-synthesis and cyclization-cleavage
丝氨酸蛋白酶(α-胰凝乳蛋白酶或枯草杆菌蛋白酶BPN')和曲霉属氨酰酶对外消旋N-乙酰基-α-氨基链烷二酸α,ω-二酯的串联作用,收率高,光学旋光性好。纯度。通过肟树脂的固相合成和环化裂解方法,将由此获得的L-α-氨基异丁二酸ω-酯方便地引入催产素类似物[Asu1,6]催产素中。
