Benzylic Arylation of 2-Methyl-5-membered Heterocycles Using TMP-Bases
摘要:
A new general Pd-catalyzed arylation of various 2-methyl-5-membered heterocycles is reported. This novel method requires Li-, Mg-, or Zn-TMP bases and allows selective metalation of the benzylic position. Subsequent Negishi cross-coupling provides the corresponding arylated heterocycles.
