We report constrained α-amino acid derivatives containing hexahydro pyrene unit using ethyl isocyanoacetate as a glycine equivalent. The required precursor 1,4,5,8-tetrakis(bromomethyl)naphthalene 3 was prepared from commercially available naphthalene-1,4,5,8-tetracarboxylic anhydride 4 in a three-step sequence. Graphical abstract Herein, we have developed a facile synthetic strategy to hexahydro pyrene
我们使用异氰基乙酸乙酯作为甘氨酸等价物报告了含有六氢芘单元的受限 α-氨基酸衍生物。所需的前体 1,4,5,8-四(溴甲基)萘3由市售的萘-1,4,5,8-四羧酸酐4按三步顺序制备。 图形概要 在此,我们通过 1,4,5,8-四(溴甲基)萘与异氰基乙酸乙酯(EICA)作为甘氨酸等价物的偶联,开发了一种简便合成六氢芘的特殊氨基酸衍生物的策略。
