Trisubstituted ureas can be synthesized in a one-pot fashion from bench-stable α-chloroaldoxime O-methanesulfonates and secondary amines under mild reaction conditions.
三取代脲可以在温和的反应条件下从稳定的α-氯代aldoxime O-甲磺酸酯和二级胺一锅法合成。
Hydroxoiridium-Catalyzed Hydroalkylation of Terminal Alkenes with Ureas by C(sp<sup>3</sup>
)−H Bond Activation
alkylation of a methyl group, on di‐ and trisubstituted ureas, with terminalalkenes by C(sp3)−Hbondactivation proceeded in the presence of a hydroxoiridium/bisphosphine catalyst to give high yields of the corresponding addition products. The hydroxoiridium/bisphosphine complex generates an amidoiridium intermediate by reaction with ureas having an N−H bond.
