Catalytic cyclization of enediynes via intramolecular nucleophilic addition was achieved with TpRuPPh3(MeCN)2PF6 and platinum dichloride, giving naphthalene-fused 2,3-dihydrofurans and -pyrroles in good yields. On the basis of experimental results, the mechanism is proposed to involve nucleophilic addition to a Ï-alkyne intermediate, followed by alkyne insertion.
利用 TpRuPPh3(MeCN)2PF6 和二氯化铂通过分子内亲核加成实现了烯炔类化合物的催化环化,以良好的产率得到了萘融合的 2,3- 二氢呋喃和吡咯。在实验结果的基础上,提出了亲核加成Ï-炔中间体,然后插入炔的机理。
