The Diverse One‐Pot Reactions of 2‐Quinolylzincates: Homologation, Electrophilic Trapping, Hydroxylation, and Arylation Reactions.

2‐Quinolylzincates were efficiently produced from the regioselective metalation reactions of quinoline with various organozincates as key intermediates. The four different types of title reactions of these intermediates under the presented reaction conditions allowed for the facile formation of the corresponding C‐2 functionalized quinolines, which are not successfully accessed through typical zincation methods. The diverse C‐2 functionalizations of quinoline are successfully achieved via 2‐quinolylzincate intermediates by the four different types of title reactions. [ABSTRACT FROM AUTHOR]
