Copper-Catalyzed Direct Syntheses of Phenoxypyrimidines from Chloropyrimidines and Arylboronic Acids: A Cascade Avenue and Unconventional Substrate Pairs
or their salts. In contrast to the general trend of delivering Suzuki–Miyaura cross-coupling products in reactions between aryl or alky halides and arylboronic acids, the substrate pairs used herein (chloropyrimidines and arylboronic acids) led to C–O bond formation under the reaction conditions. In total, 25 phenoxypyrimidines were successfully synthesized using the described protocol, 6 of which

A new method for metal‐free intramolecularCHamination has been developed. Electrochemical oxidation of 2‐pyrimidyloxybenzenes and 2‐pyrimidylthiobenzenes, which can be easily prepared from phenols and thiophenols, respectively, followed by the treatment of the resulting pyrimidinium ions with piperidine gives 2‐aminobenzoxazoles and 2‐aminobenzothiazoles, respectively.
