Synthesis of 3-amino-5H-pyrrolo[2,3-e]-1,2,4-triazines by Sonogashira/copper(I)-catalyzed heteroannulation
摘要:
A Sonogashira/copper(I)-catalyzed heteroannulation sequence was developed to convert 3,5-diamino-6-chloro-1,2,4-triazines to the corresponding 3-amino-5H-pyrrolo [2,3-e]-1,2,4-triazine derivatives in good yields. (C) 2007 Elsevier Ltd. All rights reserved.
