A base-promoted tandem SNAr/Boulton–Katritzky rearrangement is developed. It offers a simple and straightforward method for the formation of functionalized [1,2,4]triazolo[1,5-a]pyridines from 1,2,4-oxadiazol-3-amines or 3-aminoisoxazoles with 2-fluoropyridines.
开发了一种碱基促进的串联 S N Ar/Boulton-Katritzky 重排。它提供了一种从 1,2,4-恶二唑-3-胺或 3-氨基异恶唑与 2-氟吡啶形成官能化 [1,2,4]三唑并[1,5- a ]吡啶的简单直接的方法。
