clear colorless to light yellow-green liquid | [Uses]
2,2,6,6-Tetramethylpiperidine is used in the syntheses of HMP-Y1, Hibarimicinone and HMP-P1, tyrosine kinase inhibitors. | [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.
