Starting from phthalimidoalkanoylamines 1 (amino-protected derivatives of glycine, β-alanine, γ-amino butyric, δ-amino valeric, and ε-amino caproic acids), a facile synthetic method has been developed to obtain diethyl 5-alkyl(dialkyl)amino-2-aminoalkyl-1,3-oxazol-4-ylphosphonates 7, which have been further used in the preparation of phosphorylated peptidomimetics 10 and 12.
从邻苯二甲酰亚胺基链烷胺1(甘氨酸,β-丙氨酸,γ-氨基丁酸,δ-氨基戊酸和ε-氨基己酸的氨基保护衍生物)开始,已经开发了一种简便的合成方法以获得5-乙基二烷基二乙基氨基-2-氨基烷基-1,3-恶唑-4-基膦酸酯7,已进一步用于制备磷酸化拟肽10和12。
