Transition metal catalysed alkylation of pyridines and indoles
摘要:
Heating 3- or 4-acetyl pyridine with alkenes in toluene in the presence of 5-10 mol% of RuH2CO(PPh3)(3) afforded the mono- or a mixture of mono- and di-alkylated products in good yield. Alkylation of acetylindole derivatives was also achieved with similar efficiency. (C) 1997 Elsevier Science Ltd.
