A new method was developed to synthesize N-alkyl-substituted 1,2,3-triazoles gold catalyzed alkylation of vinyl ethers with mono- and unsubstituted NH-1,2,3-triazoles and benzotriazole. A hydrogen bond between the oxygen atom of the vinyl ethers, activated the gold catalyst, and the NH-1,2,3-triazoles was supposed to be generated, which selectively gave the N-alkylation products.
开发了一种新方法来合成N-烷基取代的1,2,3-三唑,即通过金催化乙烯基醚与单取代和未取代的NH-1,2,3-三唑以及苯并三唑进行烷基化反应。据推测,乙烯基醚的氧原子、活化的金催化剂与NH-1,2,3-三唑之间会形成氢键,从而选择性地生成N-烷基化产物。
