本文首次报道了一种立体特异性收敛肽精氨酸糖基化方法。最近发现的一种精氨酸糖基化激发了精氨酸修饰的兴趣,这是一种具有挑战性的修饰,因为胍基侧链的惰性。该方法使精氨酸糖苷结构收敛。在钯的催化下,糖基一步修饰精氨酸胍基团,在常温下具有较高的官能团耐受性。糖基化产物可以在几个步骤中转化为糖肽类似物。
A stereospecific convergent peptide arginine glycosylation method is reported for the first time. A recently discovered arginine glycosylation invigorated the interests of arginine modification, which has been challenging, because of the inertness of the guanidino side chain. The approach renders the arginine glycoside construction convergently. Catalyzed by palladium complex, glycals modify arginine guanidino groups in one step with high functional group tolerance at ambient temperature. The glycosylated products may be converted to glycopeptide analogues in few steps.
