reported. The requisite nitrogen functionalities of the agelastatin core have been installed by intramolecular aziridination of an azidoformate and subsequent regioselective azidation, leading to net trans-diamination of the double bond. The present synthesis also demonstrates two new protocols for the preparation of an imidazolidinone hemiaminal motif from an oxazolidinone intermediate which comprise sequential
报道了一种新的(-)-抗弹性蛋白A途径。叠氮甲酸酯的分子内叠氮化和随后的区域选择性叠氮化已安装了年龄弹性蛋白核心的必要氮官能团,从而导致双键的净反渗透。本发明还证明了从恶唑烷酮中间体制备咪唑烷酮半胱氨酸基序的两个新方案,其包括顺序的N-叔丁氧基羰基化,尿素形成,水解和氧化环化,以及直接氨解和随后的氧化环化。
