The Michael addition of 4-oxo-TMP-alkoxyaminederived Schiff bases to acrylates provides a convenient way to obtain a variety of novel and versatile alkoxyamine building blocks.

Synthesis of 3-Substituted Derivatives of 2,2,6,6-Tetramethylpiperidine-N-alkoxyamine Ethers: Novel Alkoxyamine Building Blocks. -Novel enamines of alkoxyamines are prepared starting with the O-alkylation of 4-oxo-tetramethylpiperidinyloxyl. The corresponding 3-substituted derivatives as well as synthetically interesting heterocyclic compounds are synthesized in good yields. -(FISCHER, W.; BASBAS, A.-I.; SCHOENING*, K.-U.; HAUCK, S.; Synthesis 2010, 22, 3873-3878, http://dx.doi.org/10.1055/s-0030-1258255 ; BASF AG, CH-4002 Basel, Switz.; Eng.) -M.
