A series of 10-membered cyclic enediynes trans-fused with N-protected and N-unprotected β-lactams have been stereoselectively prepared. These compounds were found to be stable toward Bergman cycloaromatization, which, on the other hand, takes place readily when the azetidinone ring is opened.
已经立体选择性地制备了与N-保护的和N-未保护的β-内酰胺反式融合的一系列10元环烯二炔。发现这些化合物对伯格曼环芳化反应是稳定的,另一方面,当氮杂环丁酮环打开时,该反应容易发生。
