5-Arylpyrrole-2-carboxylic acids are important key intermediates in the synthesis of HIV-1 entry inhibitors (such as NBD-11021 and NBD-14010). Here we present a general method for the synthesis of some 5-arylpyrrole-2-carboxylic acids in three steps starting from pyrrole. By this method, the compounds could be prepared on gram scale and without chromatographic purification.

Paragraph 0244; 0245; 0246, (2017/09/21)
The invention relates to the fields of pharmaceutical chemistry and medicine therapeutics, concretely relates to a new boric acid compounds, and a preparation method and a use thereof, and especially relates to new substituted five-membered heterocyclic boric acid and substituted benzo five-membered boric acid compounds, and a preparation method thereof. A result of bioactive screening test of the substituted five-membered heterocyclic boric acid and substituted benzo five-membered boric acid compounds having a structure represented by a formula shown in the description shows that the compounds have a proteasome inhibition effect, and can be further used for preparing medicines for treating proteasome correlated diseases.

, (2008/06/13)
Nitrogen-containing heteroaryl dioxo-butyric acid derivatives are described as inhibitors of HIV integrase and inhibitors of HIV replication. These compounds are useful in the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.

5-Arylpyrrole-2-carboxylic acids are prepared by DDQ oxidative aromatization of the corresponding ethyl 2-aryl-Δ1-pyrroline-5-carboxylate followed by basic hydrolysis.

Haloform cleavage of 2-trifluoroacetyl- and N-vinyl-2-trifluoroacetylpyrroles gives pyrrole-2-carboxylic acids and their N-vinyl derivatives in good yields; most of these compounds do not melt between 120-190 deg C, but rather decompose with CO2 evolution.
