Regio- and Chemoselective Multiple Functionalization of Pyrimidine Derivatives by Selective Magnesiations using TMPMgCl·LiCl
摘要:
Successive regio- and chemoselective magnesiations of pyrimidines using TMPMgCl center dot LiCl furnish, after trapping with various electrophiles, highly functionalized derivatives in good to excellent yields. Applications to the synthesis of antiviral and anti-inflammatory agents such as p38 and sPLA2 kinase inhibitors are reported.

serve as electrophiles in this cross‐coupling reaction. Aryl‐, heteroaryl‐, benzylic, and alkylzinc halides with sensitive functionalities, such as ester, nitrile, or ketone groups react at ambient temperature with unsaturated thioethers using a Ni catalyst. The corresponding Pd‐catalyzed reactions require slightly higher temperatures. Large‐scale cross‐coupling experiments (10–20 mmol) with N‐heterocycles
(pyridines, pyrimidines, pyrazines, pyridazines, triazines, benzothiazoles, benzoxazoles, pyrazoles, benzindazoles, quinazolines, etc.) undergo smooth Pd-catalyzedcross-coupling reactions with functionalized aryl-, heteroaryl-, benzylic-, and alkylzinc reagents using Pd(OAc)2/S-Phos as the catalytic system mostly at 25 °C. No copper salt is required to perform these reactions.
