Starting from the N,N-dibenzyl protected ß-amino acid 3 a synthesis of the C 2-symmetric racemic 2,3-diaminotetralin (4; 2,3- diamino-1,2,3,4-tetrahydronaphthalene) is reported. The key step of the procedure is a highly stereocontrolled electrophilic amination by dibenzyl azodicarboxylate.
从 N,N-二苄基保护的 ß- 氨基酸 3 开始,报告了 C 2 对称外消旋 2,3- 二氨基四氢萘 (4; 2,3- 二氨基-1,2,3,4-四氢萘) 的合成。该过程的关键步骤是用偶氮二甲酸二苄酯进行高度立体控制的亲电胺化。
