Our preparation of dimedone guides students through a Michael addition followed by a Dieckmann cyclization, basic ester hydrolysis, and thermal decarboxylation, while allowing time for mechanistic discussion and analysis of the product. The wide variety of techniques covered led this to be a pedagogically diverse experiment. This task is thoroughly tested and suitable for a 6 hour laboratory class (with a 1 hour lunch break) or two 3 hour stand-alone sessions.  aSynthesis  aEquilibrium Reactions NMR Spectroscopy Hands-On Learning/Manipulatives  aOrganic Chemistry Laboratory  aInstruction Second-Year Undergraduate  aUpper-Division Undergraduate uhttps://pubs.acs.org/doi/epdf/10.1021/acs.jchemed.3c00069 cPER 00104070aRIEBPLbRIEBPLd2023-11-16l0o540.7r2023-11-16 00:00:00w2023-11-16yPER c44881d44880
