J. Einhorn et al., SYNTHESIS AND RESOLUTION OF A CHIRAL ANALOG OF 2,2,6,6-TETRAMETHYLPIPERIDINE AND OF ITS CORRESPONDING NITROXIDE, Tetrahedron letters, 39(17), 1998, pp. 2565-2568
The novel C-2 symmetric chiral amine trans-2,6-dimethyl-2,6-diphenylpi
peridine has been synthesized via two successive nitrone nucleophilic
addition-oxidation sequences, followed by reduction of the intermediat
e nitroxide. hue enantiomers have been obtained via resolution with ma
ndelic acid. (C) 1998 Elsevier Science Ltd. All rights reserved.
