The N-tert-butylcarbamoyl serves as a useful, readily removable (LiOH/MeOH/THF) new directed metalation group for the synthesis of 2-substituted pyrroles and indoles.
Preparation of 2-substituted pyrroles and indoles by regioselective alkylation and deprotection of 1-(2-trimethylsilyllethoxymethyl)pyrrole and 1-(2-trimethylsulylethoxymethyl) indole

After N-alkylation of pyrrole and indole with 2-trimethylsilylethoxymethyl chloride the products of the reaction could be regioselectively deprotonated with n-butyllithium at the 2-position.Reaction of the resulting anions with acid chlorides, lactones, silyl chlorides or aldehydes gave addition products, some of which were deprotected to the parent pyrrole or indole using anhydrous tetra-n-butylammonium fluoride.
