Inverse electron demand Diels-Alder reactions of 4,6-dimethyl-2-oxo-2H-pyran-5-carboxylic acid esters and morpholino enamines: regiospecific preparation of 3- or 4-substituted-2,6-dimethylbenzoates
Inverse electron demand Diels-Alder reactions of 4,6-dimethyl-2-oxo-2H-pyran-5-carboxylic acid esters and morpholino enamines: regiospecific preparation of 3- or 4-substituted-2,6-dimethylbenzoates
Precursors to benzyl compounds, useful in the manufacture of pyrethroid insecticides, are prepared by regiospecific addition of an enamine to a heterocyclic diene accompanied by elimination of volatile by-products.
