scheme or table, p. 3135 - 3146 (2010/06/13)
A facile synthetic approach to the direct preparation of 2-pyridyl and 3-pyridylzinc bromides has been demonstrated using Rieke zinc with 2-bromopyridine and 3-bromopyridine, respectively. A variety of different electrophiles have been coupled with the resulting organozinc reagents to give the corresponding cross-coupling products in moderate to good yields.

Acetylenic acetals and ketals have been reacted with aryl and vinyl halides to generate hydroarylation and hydrovinylation products. The reaction proceeds with high regioselectivity. The carbopalladation step appears to be mainly controlled by steric effects and the new carbon-carbon bond is generated preferentially on the carbon bearing the acetal group. The reaction has been employed to develop a regioselective synthesis of 3-aryl and 3-vinylquinolines.
A SIMPLE REGIOSELECTIVE PREPARATION OF 2- OR 3-SUBSTITUTED QUINOLINE DERIVATIVES VIA DIALKYLQUINOLYLBORANES
Ishikura, Minoru,Oda, Izumi,Terashima, Masanao
, p. 2375 - 2386 (2007/10/02)
Various quinoline derivatives possessing a substituent at the 2- or 3-position were prepared by the reaction of dialkylquinolylboranes and organic bromides in the presence of a palladium catalyst.
