Convenient Synthesis and Transformation of 2,6-Dichloro-4-iodopyridine
摘要:
[GRAPHICS]We describe a convenient scalable synthesis of 2,6-dichloro-4-iodopyridine and demonstrate its utility by stepwise elaboration to a number of 2,4,6-trisubstituted pyridines.

Various pyridine, quinoline, isoquinoline, and pyrimidine N-oxides were converted to their corresponding alpha-N-aryltriflamidoheteroarenes in good yield by treatment with N-aryltriflimides, both neat and in solution, at temperatures ranging from rt to 100 degrees C.
