ChemInform Abstract: Synthesis of 5‐Substituted Quinolin‐8‐ols.

Abstract

Synthesis of 5-Substituted Quinolin-8-ols.-The title compounds (IV) and (VII) are prepared from a haloquinoline such as (I) with arylboronic acids such as (II) or with (V) under typical Suzuki reaction conditions, followed by catalyzed benzyloxy group deprotection. Bromide is the best of the three halides employed. Chlorides are inactive. The products are of interest as ligands in the formation of metal chelates with axial chirality. - (NAKANO, Y.; IMAI, D.; Synthesis (1997)
