PROCESS FOR THE PREPARATION OF THIOETHER-SUBSTITUTED AROMATIC KETONES
-
, (2008/06/13)
The preparation of aromatic ketones substituted with a thioether group at the ortho position is accomplished by the initial reaction of an aromatic nucleus substituted with a halide and an ortho nitro group with a nitroalkane in the presence of a hydroxide base. The resulting ortho-nitroalkyl nitroarene compound is converted to the corresponding ortho-nitroaryl ketone by an oxidative Nef reaction. The aromatic nitro group of the ortho-nitroaryl ketone is replaced with a thioether group by reaction with a thiolate anion, most preferably under phase-transfer conditions. Aromatic ketones may be used to prepare various pharmaceutical and herbicidal compounds.

Addition of nitroalkanes toortho-halonitrobenzenes: A new synthesis of 4-chloro-7-(trifluoromethyl)quinoline

, p. 1093 - 1096 (2007/10/02)
Base-mediated reaction of ortho-nitroaryl chlorides and fluorides with nitroalkanes followed by an oxidative Nef reaction provides aryl ketones. With this simple procedure, methylketone 6 was prepared in 91% yield. 6 was then converted in three steps (60-65% yield) to 4-chloro-7-(trifluoromethyl)quinoline (2), an intermediate in the synthesis of the antihypertensive agent losulazine (U-54,669, 1).
