N-sulfonyl-1,2,3-triazoles, which allowed the efficient diastereoselective construction of various functionalized and synthetically challenging bridged ring systems. This simple, direct transformation had a broad substrate scope and excellent functional group tolerance. The highly strained polycyclic bicyclo[2.2.2]octa[b]indole core of fruticosine was synthesized efficiently using this methodology.
在这里,我们描述了N-磺酰基-1,2,3-三唑的铑催化桥接 (3+2) 环加成级联反应,这使得各种功能化和合成具有挑战性的桥接环系统的有效非对映选择性构建成为可能。这种简单、直接的转化具有广泛的底物范围和出色的官能团耐受性。使用该方法有效地合成了果糖苷的高应变多环双环[2.2.2]octa[ b ]吲哚核。
