The present invention relates to a heteroaryl derivative or a pharmaceutically acceptable salt thereof, a preparation method therefor, and a pharmaceutical composition for preventing or treating diseases associated with PI3 kinases, containing the same as an active ingredient. The heteroaryl derivative according to the present invention has an excellent effect of selectively inhibiting PI3 kinases, thereby being useful in preventing or treating PI3 kinase diseases such as: cancers, autoimmune diseases, and respiratory diseases.
A convenient and efficient synthesis of substituted quinolines via a simple one-pot reaction of an aniline, an aromatic aldehyde, and an enolizable aliphatic aldehyde in the presence of the iridium catalyst [IrCl2H(cod)]2 under oxygen as an oxidant was developed. The reaction proceeds with Mannich-type imine formation followed by nucleophilic addition to give β-amino aldehydes. Dehydrative cyclization takes place to give dihydroquinoline, which is then dehydrogenated by aerobic oxidation to give 2-aryl-3-alkylquinolines. Dialkylquinolines were obtained by the reaction with anilines and aliphatic aldehydes in good yields.

A mild, efficient, and general method for the synthesis of substitutedquinolines via a molecular iodine-catalyzed one-pot domino reaction of imines with enolizable aldehydes has been described.
This paper describes a visible-light-mediated oxidative cyclization of 2-aminobenzyl alcohols and secondaryalcohols to produce quinolines at room temperature. This photocatalytic method employed anthraquinone as an organic small-molecule catalyst and DMSO as an oxidant. According to this present procedure, a series of quinolines were prepared in satisfactory yields.
A convenient and efficient synthesis of substituted quinolines in a simple one-pot reaction of an arylamine 1, an aromatic aldehyde or aliphatic aldehyde 2 and an aliphatic aldehyde 3 in the presence of transition metal complexes or Lewis acids was developed. Among them, the iridium catalyst [Ir(cod)Cl] 2 catalyzed the reaction most efficiently.
