A convenient synthesis of trisubstituted pyrido[2,3-d]pyrimidin-7-ones
摘要:
A novel, highly efficient and scalable route for the synthesis of trisubstituted pyrido[2,3-d]pyrimidin-7-ones was developed. The target compounds were synthesized in five steps from readily available reagents in about 40% overall yield. (C) 2003 Elsevier Science Ltd. All rights reserved.
