Multiple Regioselective Functionalizations of Quinolines via Magnesiations
摘要:
A wide range of polyfunctionalized quinolines was prepared via chemo- and regioselective magnesiation reactions using appropriate Mg reagents, such as i-PrMgCl center dot LiCl, MesMgBr center dot LiCl, Mes(2)Mg center dot 2LiBr, TMPMgCl-LiCl, and TMP2Mg center dot 2LiCl. An application to the total synthesis of the biologically active compound talnetant was performed (six steps, 28%).
A dibromomethyl moiety is converted to a sulfonylmethyl moiety by treatment with a sulfinic acid salt. For example, (methyl-sulfonyl)methyl bromo-quinoline is prepared by the treatment of dibromomethyl bromo-quinoline with a sulfinic acid salt.

An activation energy ray-sensitive composition permitting development with neutral water. Provided is an activation energy ray-sensitive composition characterized by comprising a dispersion which comprises an aqueous solution of a water-soluble resin, and an acid former dispersed in the aqueous solution in the form of fine powder, the acid former being insoluble or sparingly soluble in water and generating an acid by the action of activation energy rays, and an acid-reactive insolubilizing agent dissolved or dispersed in the dispersion and insolubilizing the water-soluble resin by the action of the acid.
