group on the anomeric position are a challenging class of SAAs to synthesize due to the inherent instability of glycosylamines. We developed a novel synthetic strategy towards both furanoid and pyranoid δ-SAAs of this type, based on a Curtius rearrangement. The latter reaction, which is known to proceed with retention of configuration, was performed on carboxylic acids derived from the oxidation of
由于糖基胺固有的不稳定性,在异头位置带有胺基的糖氨基酸 (SAA) 是一类难以合成的 SAA。我们基于 Curtius 重排开发了一种针对此类呋喃和吡喃 δ-SAA 的新型合成策略。已知以保留构型进行的后一反应是在衍生自糖苷伯羟基氧化的羧酸上进行的。亮氨酸脑啡肽类似物是通过用呋喃类和吡喃类 δ-SAA 替换母体亮脑啡肽五肽中的 Gly-Gly 部分来制备的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
