Generation and alkylation of carbanions .alpha. to the nitrogen of amines by a new metallation procedure
摘要:
Treatment of a tertiary amine having a pendent o-iodobenzyl group on nitrogen with SmI2 generates alpha-amino organosamarium, which reacts with electrophiles giving the corresponding C-C bound formation products in good yield.

Disclosed are the ERK inhibitors of Formula (I): (Formula (I)) and the pharmaceutically acceptable salts thereof. All substitutents are as defined herein. Also disclosed are methods of treating cancer using the compounds of Formula (I).
A rapid synthesis of various 9-aryl derivatives of quinine is presented. They are obtained via coupling reactions of functionalized arylmagnesium halides and 9-chloroquinine.

deuterium can act as a protecting group to prevent unwanted 1,5-hydrogen atom transfer to aryl and vinyl radical intermediates was examined in the context of the generation of α-aminoalkyl radicals in a pyrrolidine ring. Intra- and intermolecular radical trapping following hydrogen atom transfer provides an illustration of the use of the primary kinetic isotope effect in directing the outcome of synthetic
Radicals derived from N-(2-iodobenzyl)‘protected’ amines undergo a 1,5-hydrogenshift to give more stable α-amino radicals, which can be subsequently trapped by electron deficient alkenes.
