Metallation in connection with cross-coupling reactions. Coupling of hindered aryls for the synthesis of 4-phenylpyridines as part of Streptonigrin and Lavendamycin analogues
摘要:
The synthesis of the C-D ring system of Streptonigrin and Lavendamycin 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.
