Chemische Eigenschaften
WHITE TO LIGHT YELLOW CRYSTALLINE POWDERVerwenden
2-Coumaranone has been used to study the effects of coumarins on 7,12-dimethyibenz(a)anthracene induced neoplasia of the rat mammary gland. It was employed as probe for detecting enzymes which hydrolyze 2-hydroxybenzofuran structures.Synthesis Reference(s)
The Journal of Organic Chemistry, 47, p. 2491, 1982 DOI: 10.1021/jo00133a055Synthese
Preparation of 2-coumarone (I) comprises reacting cyclohexanone (II) with carboxyl-containing acylating agent (III) to methyl 2-(2-oxo-cyclohexyl)-2-hydroxy-acetate (IV) and optional dehydration to a mixture (V) of methyl 2-oxo-cyclohexylidene-acetate and the enol-lactone of the acid; or direct conversion of (I) to (V); and catalytic gas phase dehydrogenation of (IV) or (V) to (I).
