Descripción general

2,2,6,6-Tetramethylpiperidineis a hindered secondary amine that is used to prepare metallo-amide bases and selective generation of silylketene acetals.

Aplicación

2,2,6,6-Tetramethylpiperidine can be used as a reactant to synthesize:
  • Allylated tertiary amines via allylic amination of allylic chlorides.
  • Hydroxylamines via oxidation in the presence of oxone as an oxidant.
  • Sulfenamide compounds by reacting with heterocyclic thiols in the presence of iodine as an oxidant.
  • N-methylated amines via N-methylation by reacting with CO2 and phenylsilane.
  • Propargylamines via three-component Mannich coupling reaction with aldehydes and alkynes.

The reaction pathways of lithium 2,2,6,6-tetramethylpiperidide (LiTMP)-mediated deprotonative metalation of methoxy-substituted arenes were investigated. Importantly, it was experimentally observed that, whereas TMEDA has no effect on the course of the reactions, the presence of more than the stoichiometric amount of
