Reported herein is the one-pot synthesis of trifluoromethylated amines at room temperature using the bench-stable (Me4N)SCF3reagent and AgF. The method is rapid, operationally simple and highly selective. It proceeds via a formal umpolung reaction of the SCF3with the amine, giving quantitative formation of thiocarbamoyl fluoride intermediates within minutes that can readily be transformed to N-CF3. The mildness and high functional group tolerance render the method highly attractive for the late-stage introduction of trifluoromethyl groups on amines, as demonstrated herein for a range of pharmaceutically relevant drug molecules.

A unique combination of CuI and CsOAc was found to catalyze aryl amination under mild conditions. The reaction takes place at room temperature or at 90 °C with broad functional group compatibility. The intramolecular reaction was able to form five-, six-, and seven-membered rings with various protecting groups on the nitrogen atom. The scope of the intermolecular amination, as well as its applications to unsymmetrical N,N′-dialkylated phenylenediamines, was investigated.

Disclosed herein is a species of peptide and non-peptide inhibitors of Akt, an oncogenic protein. Beginning with 0 a residue of Akt target substrate GSK-3, the functional domains of the GSK-3 residue were characterized. Functionallv homologous non-peptide groups were substituted for the amino acids of the GSK-3 creating a hybrid peptide-non-peptide and non-peptide compounds capable of binding to Akt. The non-peptide compounds show increased stability and rigidity compared to peptide counterpartsand are less susceptible to degradation. The bound non-peptide compounds exhibit an inhibitory effect on Akt, similar to peptide-based Akt inhibitors.

Amplification, overexpression, and elevated activation of Akt have been detected in many human malignancies making it an important target for cancer therapy. The Akt substrate-binding site offers a large number of potential interactions to an appropriatel

(Equation presented) A mild intermolecular copper-mediated amination of aryl iodides has been developed. The reaction takes place at room temperature or heating at 90°C and tolerates halogens attached to the aromatic ring. Its synthetic applications include a synthetic protocol for unsymmetrical N,N′-dialkylated phenylenediamines and both a stepwise and a general synthetic method for N-aryl secondary amines via Ns-anilides (readily obtained by reaction of the Ns-amide).
