|Section2= |Section3= |Section7= |Section8= }} 2,6-Dimethylpiperidines are chemical compounds with the formula C5H8(CH3)2NH. Three stereoisomers exist: the achiral (''R'',''S'')-isomer and the chiral (''R'',''R'')/(''S'',''S'') enantiomeric pair. Dimethylpiperidines are derivatives of the heterocycle piperidine, wherein two hydrogen atoms are replaced by methyl groups. The 2,6-dimethylpiperidines are prepared by reduction of 2,6-dimethylpyridine (2,6-lutidine). The achiral isomer is the predominant isomer produced in this reaction. The 2,6-dimethylpiperidines are of interest for their conformational properties. The (''R'',''S'')-isomer exists largely in the chair conformation with equatorial methyl groups. The (''R'',''R'')/(''S'',''S'')-isomers are attractive chiral secondary amine building blocks.〔Einhorn, J.; Einhorn, C.; Ratajczak, F.; Durif, A.; Averbuch, M.-T. and Pierre, J.-L., "Synthesis and resolution of a chiral analog of 2,2,6,6-tetramethylpiperidine and of its corresponding nitroxide", Tetrahedron Letters, 1998, volume 39, pages 2565-2568〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2,6-Dimethylpiperidine」の詳細全文を読む スポンサード リンク
