for the synthesis of 1,3‐di‐ and 1,3,4‐trisubstituted β‐carbolines through an unprecedented one‐pot triple‐orthogonal‐metal relay catalysis, and 1,3‐disubstituted 4‐hydroxy‐β‐carbolines through a one‐pot bimetallic relay catalysis from readily accessible 3‐(2‐aminophenyl)‐5‐hexenyn‐3‐ols. These strategies were elaborated to enable the synthesis of benzofuro[2,3‐c]pyridines, benzothieno[2,3‐c]pyridines
提出了一种通过空前的一锅三正交金属中继催化合成1,3-二取代和1,3,4-三取代的β-咔啉和1,3-二取代的4-羟基通过容易获得的3-(2-氨基苯基)-5-hexenyn-3-ols通过一锅双金属中继催化作用生成β-咔啉。精心设计了这些策略,可以合成苯并呋喃[2,3- c ]吡啶,苯并噻吩并[2,3- c ]吡啶和异喹啉,否则需要多步合成。

A novel Rh(iii)-catalyzed cascade C-H activation/cyclization approach to access isoquinoline derivatives from benzimidates and available allyl carbonates with the liberation of H2 has been realized. Allyl carbonates were first used as a versatile and universal C2 synthon to synthesize this biological activity skeleton via an efficient and practical process just within 1 h.
