Transformations of electrophilic reagents in a diethyl phosphite-potassium carbonate-ethanol system
摘要:
Transformations of alkyl halides, aldehydes, and activated alkenes in a (EtO)(2)PHO-K2CO3-EtOH heterophase system were studied. The reactions are catalyzed by EtOK that formed and follow the known schemes of the interaction of hydrophosphoryl compounds with electrophiles.
QuadrupleFunctionalization: A one-pot regioselective [3+2] cycloaddition platform of fluorinatednitrileimines with dicyanoalkenes was established to produce a broad variety of fully substituted N1-aryl 3-di/trifluoromethyl-4/5-cyanopyrazole pharmacophores.
