-
Paragraph 0152-0154, (2020/03/09)
The present disclosure relates to a novel piperidine-2,6-dione derivative and a use thereof and, more specifically, to a piperidine-2,6-dione derivative compound having a structure of a thalidomide analog. A compound of chemical formula 1 according to the present disclosure specifically binds with CRBN protein, and is involved in functions thereof. Therefore, the compound of the present disclosure can be favorably used in the prevention or treatment of leprosy, chronic graft versus host disease, an inflammatory disease, or cancer, which are caused by actions of CRBN protein.

A convenient two-step synthesis of ethyl 4-hydroxy-2-methylquinoline-3-carboxylate derivatives has been developed starting from commercially available 2-aminobenzoic acids. In step 1, the anthranilic acids are smoothly converted to isatoic anhydrides using solid triphosgene in THF. In step 2, the anhydride electrophiles are reacted with the sodium enolate of ethyl acetoacetate, generated from sodium hydroxide, in warm N,N-dimethylacetamide resulting in the formation of substituted quinolines. A degradation–buildup strategy of the ethyl ester at the 3-position allowed for the construction of the α-hydroxyacetic acid residue required for the synthesis of key arylquinolines involved in an HIV integrase project.
