2,2,6,6-Tetramethylpiperidine Chemical Properties,Usage,Production

Chemical Properties

clear colorless to light yellow-green liquid

Uses

2,2,6,6-Tetramethylpiperidine is a hindered base used to prepare metallo-amide bases and selective generation of silylketene acetals. It is used in the preparation of hibarimicinone, (Z)-silylketene acetal and 4-substituted quinazoline. It acts as a precursor to Lithium tetramethylpiperidide and (2,2,6,6-Tetramethylpiperidin-1-yl)oxyl radical.

Uses

2,2,6,6-Tetramethylpiperidine is used in the syntheses of HMP-Y1, Hibarimicinone and HMP-P1, tyrosine kinase inhibitors.

Uses

The lithium amide has been used to efficiently ortho deprotonate pyridine-3-carboxamides.

Preparation

Many routes for the synthesis of TMP have been reported. One method starts with a conjugate addition reaction of ammonia to phorone. The intermediate triacetone amine is then reduced in a Wolff-Kishner reaction.
