New dual inhibitors of EGFR and HER2 protein tyrosine kinases
摘要:
A novel series of dual EGFR and HER2 inhibitors based on the pyrrolo[2,1-f][1,2,4]triazine nucleus is described. A general route toward their synthesis, which enables functionalization at multiple sites, has been developed. Biological evaluation in enzymatic and cell-based assays has identified a series of C-6 carbamates with potent biochemical and cellular activities.
An efficient electrophilic N-amination utilizing in situ generated chloramine under phase transfer conditions
摘要:
An efficient, one-pot, phase transfer N-amination technology was developed. The protocol utilizes chloramine, an inexpensive and safe electrophilic aminating agent potentially viable for commercial manufacturing. (c) 2006 Elsevier Ltd. All rights reserved.
