In this communication we describe a novel strategy for the formation of valuable diaryl and arylalkylketones from acyl hydrazides. A wide variety of ketones are prepared and the mild reaction conditions allow for the use of a range of functionalities, especially in the synthesis of diaryl ketones.

Azetidinone derivatives of formula (I) in which R.sup.1 and R.sup.2, which may be the same or different, is each selected from hydrogen or C.sub.(1-8) alkyl; R.sup.3 is C.sub.(1-8) alkyl or C.sub.(3-8) cycloalkyl each of which may be optionally substituted; X is a linker group; Y is an aryl group; and n is 0, 1 or 2; and excluding benzyl (4-methylthio-2-oxo-azetidin-1-yl)acetate are inhibitors of the enzyme Lp PLA2 and are of use in therapy, in particular treating atherosclerosis.
