2,2,2-Trifluoroethyl Chlorooxoacetate—Universal Reagent for One-Pot Parallel Synthesis of N1-Aryl-N2-alkyl-Substituted Oxamides
摘要:
A one-pot parallel synthesis of N-1-aryl-N-2-alkyl-substituted oxamides with 2,2,2-trifluoroethyl chlorooxoacetate was developed. The synthesis of a library of 45 oxamides revealed higher efficiency of this reagent over the known ethyl chlorooxoacetate. The reagent was successfully used to prepare the known oxamide-containing HIV entry inhibitors.

The direct amidation of esters with 4-amino-2,2,6,6-tetramethylpiperidine was achieved by computer-controlled microwave irradiation in toluene. The microwave protocol allowed the new amides to be prepared in three hours rather than the three days required by traditional thermal methods.

Soluble-type small-molecule CD4 mimics as HIV entry inhibitors
Several small molecule CD4mimics have been reported previously as HIV-1 entryinhibitors, which block the interaction between the Phe43 cavity of HIV-1 gp120 and the host CD4. Known CD4mimics such as NBD-556 possess significant anti-HIV activity but are less soluble in water, perhaps due to their hydrophobic aromatic ring-containing structures. Compounds with a pyridinyl group in place of the phenyl
