<p>1,2-Dimethylpiperidin-4-one is a chiral compound that can be used to make optically active compounds. It is an important intermediate in the synthesis of piperidones. The 1,2-dimethylpiperidin-4-one has two diastereomers, which are called cis and trans. The cis configuration has a methyl group in the same plane as the amine group, whereas the trans configuration has the methyl group in a different plane. The cis configuration is more stable than the trans one and this is because it is less sterically hindered by the bulky groups on either side of it. This means that if you want to make an optical pure compound, it will be easier to do so using cis rather than trans 1,2-dimethylpiperidin-4-one.</p>
