Synthesis of bis-fused benzofuran derivatives by the implementation of palladium-mediated intramolecular cyclization is described. To our knowledge, this is the first report of the synthesis of bis-fused benzofuran by this protocol. Bisbenzoxepine and bisbenzoxocine derivatives were also synthesized by the application of two-directional ring-closing metathesis. palladium catalyst - Grubbs catalyst
描述了通过钯介导的分子内环化的合成双稠合苯并呋喃衍生物。据我们所知,这是该方案合成双稠合苯并呋喃的第一份报告。还通过应用双向闭环复分解反应合成了双苯并xepine和双苯并xocine衍生物。 钯催化剂- Grubbs催化剂-分子内环化-双向闭环复分解- 5-外型- TRIG -苯并呋喃-氧杂七环- oxocine
