Synthesis and cross coupling of a highly substituted 2-pyridylboronate: application to the large scale synthesis of a mineralocorticoid antagonist
摘要:
The large scale synthesis of a functionalized 2-pyridylboronate 8 and optimization of its Suzuki-Miyaura coupling to chloropyrazoline (R)-7 to provide a scalable synthesis of mineralocorticoid antagonist (R)-1 is described. (C) 2011 Elsevier Ltd. All rights reserved.
