palladium-catalyzed intramolecular Trost–Oppolzer type Alder-ene strategy was developed for the synthesis of carbazoles and cyclopenta[b]indoles from easily accessible(3-allyl-1H-indol-2-yl)methyl acetates. This strategy was extended for the synthesis of naphthalenes and dibenzobenzofurans as well. In addition, a short synthesis of antibacterial and antifungal natural product glycozoline and its analogues was also
开发了一种有效的钯催化的分子内Trost-Oppolzer型Alder-ene策略,用于从易于获得的(3-烯丙基-1 H-吲哚-2-基)乙酸甲酯合成咔唑和环戊[ b ]吲哚。该策略也扩展到了萘和二苯并呋喃的合成中。另外,还实现了抗菌和抗真菌天然产物糖唑啉及其类似物的短合成。
