Metallation in connection with cross-coupling reactions. Coupling of hindered aryls for the synthesis of 4-phenylpyridines as part of Streptonigrin and Lavendamycin analogues

Article abstract of DOI:10.1016/0022-328X(95)05979-Y

The synthesis of the C-D ring system of Streptonigrin and Lavendamycln alkaloid analogues by cross-coupling under Suzuki's conditions has been studied. Steric hindrance is the main problem. It has been solved either by using strong bases or working in a sealed tube under pressure.
