Iodo- or 2-bromopyridine N-oxides were readily magnesiated with i-PrMgCl ? LiCl via the iodine or bromine-magnesium exchange. The bromine adjacent to pyridine N-oxide (at the 2- or 6-position) can be regioselectively magnesiated in the presence of other position substituted halogens. This method was tested in various substituted pyridine N-oxide systems, and has been successfully applied to the total synthesis of caerulomycins E and A.

The comparative studies have been carried out on reactivities of pyridine, quinoline, isoquinoline, and their BF3 complexes, their N-oxides, and their N-oxide-BF3-complexes, towards the electrophilic reaction through α-deprotonation.
IPSO SUBSTITUTION OF HETEROCYCLIC TRIMETHYLSILYL CARBOXYLATES BY CARBON ELECTROPHILES
Effenberger, Franz,Koenig, Joachim
, p. 3281 - 3288 (2007/10/02)
Trimethylsilyl esters 1 of heterocyclic carboxylic acids having the ester group in the α-position to an azine nitrogen atom react with aldehydes or ketones through ipso substitution of the ester group to give (trimethylsiloxy)-alkyl-substituted heterocyclic products in good yields.
