supporting information, p. 6053 - 6056 (2013/10/22)
A facile method of regioselective formylation of disubstituted benzene via in situ deprotonation/metalation using n-BuLi/TMEDA/DIPA has been developed. Effect of different electron withdrawing and electron donating substituents in 1,3-interrelated aromatic system was studied; the metalation mostly occurred at the 2-position to afford the desired products in high yields.
Fluorine as an ortho-directing group in aromatic metalation: A two step preparation of substituted benzo[b] thiophene-2-carboxylates
Bridges, Alexander J.,Lee, Arthur,Maduakor, Emmanuel C.,Eric Schwartz
, p. 7499 - 7502 (2007/10/02)
A simple 2-step synthesis of B-ring substituted benzo[b]thiophene-2-carboxylates from aryl fluorides has been developed. The route involves a selective lithiation ortho to fluorine, followed by formylation, and subsequently, displacement of fluorine with
