The first asymmetric synthesis of the naturally-occurring cyclopropane amino acid carnosadine, 1, has been carried out. Starting from the previously available chiral intermediate 2, appropriate amine protection and side-chain modifications permitted introduction of the key guanidyl substituent in a short and efficient synthesis to give the title compound in five steps and 45% overall yield.
已经进行了天然存在的环丙烷氨基酸卡诺沙定1的第一次不对称合成。从先前可用的手性中间体2开始,适当的胺保护和侧链修饰允许在短而有效的合成中引入关键的胍基取代基,从而分五个步骤得到标题化合物,且总产率为45%。
