  First metalation of aryl iodides: directed ortho-lithiation of iodopyridines, halogen-dance, and application to synthesis

  摘要：

  Metalation of iodopyridines was successfully achieved by LDA at low temperature. In many cases, lithiation is ortho directed by the iodo group which subsequently ortho-migrates very fast to give stabilized iodolithiopyridines. This procedure was applied to 2-fluoro-and 2-chloro-3-iodopyridines, 3-fluoro-4-iodopyridine, and 2-chloro-3-fluoro-4-iodopyridine. The resulting lithio intermediates were obtained in high yields before being reacted with electrophiles leading to various polysubstituted pyridines. Some of these iodopyridines were used as key molecules for the synthesis of fused polyaromatic alkaloids. Thus, perlolidine, delta-carbolines, and 2,10-diazaphenanthrenes were readily prepared in few steps taking advantage of the iodo reactivity for heteroring cross-coupling.

  A robust and practical protocol for preparing alkyl aryl ethers has been developed, which relies on using two types of ligands to promote Cu-catalyzed alkoxylation of (hetero)aryl halides. The reaction scope is very general for a variety of coupling partners, particularly for challenging secondary alcohols and (hetero)aryl chlorides. In case of coupling with aryl chlorides and bromides, two oxalic
