3,4-Fused tricyclic indole scaffolds are ubiquitous in bioactive natural products and pharmaceuticals. A new protocol for the synthesis of 3,4-fused tricyclic indoles has been developed through cascade carbopalladation and C–H amination with N,N-di-tert-butyldiaziridinone. The protocol allows access to a range of 3,4-fused tricyclic indoles, including those containing various linkers and fused with
3,4-融合的三环吲哚支架在生物活性天然产物和药物中普遍存在。通过级联碳氢键合和N,N-二叔丁基二氮杂吡啶酮的CH-H胺化反应,已开发出一种新的3,4-稠合三环吲哚合成方法。该协议允许访问一系列3,4-稠合的三环吲哚,包括那些包含各种接头并与中等大小的环稠合的吲哚。Rucaparib可以通过该反应合成,为FDA批准的癌症药物提供了一种有利的合成方法。
