Abstract
Abstract The synthesis of gem-dimethylnorbornanones is described. One synthetic pathway after a Diels-Alder reaction involves the transformation of the nitro group into the oxo group with subsequent methylation into the geminal dimethyl product. A shorter way by [4+ 2]- cycloaddition of cyclopentadiene with a suitable dimethylated dienophile (eg 2-methyl-1- nitropropene) failed, probably by steric hindrance of the dienophile. 7-Oxanorbornanones, ...
