Questions And Answer

Description
Cyclobutanone is an organic compound with a four-membered cyclic ketone. It is used in preparation of cyclobutane derivatives, as a starting material for aminocyclobutanecarboxylic acid through sulfonyloxiranes, to prepare dihydro-furan-2-one in presence of polystyrene-bound phenylselenic acid as catalyst. It is also involved in the photochemical synthesis of nucleoside analogues such as bicyclic nucleosides and isonucleosides. Furthermore, it is used to synthesis fatty acid, 2-oxo-cyclobutane undecanoic acid, which is used in the development of an enzyme-linked immunosorbent assy for the detection of irradiated foods.
