Spirocyclic NK1 antagonists I: [4.5] and [5.5]-Spiroketals
摘要:
A series of novel spiroketal-based NK1 antagonists is described. The effect of modifications to the spiroether ring and aromatic substituents are discussed, leading to the identification of compounds with high affinity and excellent CNS penetration.

medicinal chemistry. Moreover, organosilanes are valuable synthetic intermediates for fine chemicals and materials. Transition metal-catalyzed C-H silylation has become an important strategy for C-Si bondformations. However, despite the great advances in aromatic C(sp2)-H bond silylations, catalytic methods for aliphatic C(sp3)-H bond silylations are relatively rare. Here we report a pincer ruthenium

continuous‐flow method for the regioselective arylation of fluoroarenes and fluoropyridines has been developed. The telescoped procedure reported here consists of a three‐step metalation, zincation, and Negishi cross‐coupling sequence, providing efficient access to a variety of functionalized 2‐fluorobiaryl products. Precise temperature control of the metalation step, made possible by continuous‐flow technology
