INTERACTION OF VICINAL N-METHYL AND C2-ISOPROPYL SUBSTITUENTS IN 3-KETOPIPERIDINES: RING CONFIGURATION AND STEREOCHEMISTRY OF CARBONYL REACTIONS

Katvalyan, G. T.,Mistryukov, E. A.,Shashkov, A. S.

, p. 776 - 781 (1990)

The cis- and trans-1,5-dimethyl-2-isopropyl-3-piperidones were synthesized.Their configurations were determined using 1H and 13C NMR spectroscopy.The stereochemistry of the hydride and catalytic reduction of the resulting 3-piperidones was studied.
