A simple, convenient and green synthetic approach to diverse fused tricyclic xanthines has been developed via gold(I) complex-catalyzed intramolecular hydroamination or silver(I)-catalyzed isomerization-hydroamination of terminal alkynes under microwave irradiation in water. The first synthesis of N9-annelated xanthines has also been reported.
通过金(I)络合物催化的分子内氢胺化反应或银(I)催化的炔烃在水中的微波辐射异构化-氢化胺化反应,开发了一种简便,便捷且绿色的合成各种稠合三环黄嘌呤的方法。还已经报道了N9-退火的黄嘌呤的首次合成。
