3,5-Dimethylpiperidines are chemical compounds with the formula C5H8(CH3)2NH. Two diastereomers exist: the achiral R,S isomer and the chiral R,R/S,S enantiomeric pair. 3,5-Dimethylpiperidine is a precursor to tibric acid.
The compound is typically prepared by hydrogenation of 3,5-dimethylpyridine. Both diastereomers also arise from the reduction of 3,5-dimethylpyridine with lithium triethylborohydride.[1]
