Former spectra of novel 2,5-disubstituted dihydrofuroketones have shown interesting 5J coupling. This research will examine the J coupling present in 1-(5-tert-butyl-2-methyl-2,5-dihydrofuran-3-yl) ethanone wherein the ring is substituted with tert-butyl and methyl groups. This compound is synthesized by a variety of reactions including Henry Addition, acetylation, deacetylation, Grignard reaction, Michael Addition, and Intramolecular Silyl Nitronate Cycloaddition (ISNC). Examination of the steric effects of the various substituted functional groups will allow further assessment of the 5J coupling.
