The present invention relates to dihydropyrrole compounds that are useful for treating cellular proliferative diseases, for treating disorders associated with KSP kinesin activity, and for inhibiting KSP kinesin. The invention also related to compositions which comprise these compounds, and methods of using them to treat cancer in mammals.
Syntheticroutes to α,α-disubstituted allylamines have been examined. Racemic compounds were conveniently prepared by thermal Overman rearrangements of primary allyl alcohols with trisubstituted double bonds, but rearrangement of these substrates by the only commercially available compound known to catalyze enantioselective Overman rearrangements, the cobalt oxazoline palladacycle (R)-COP-Cl, failed
Abstract Various α,α-methyl aryl allylic amines were synthesized from γ-aryl crotyl alcohols via thermal Overman rearrangement. Noteworthy is that the presence of the electron withdrawing groups at aryl group causes substantial increases in the reaction rates and product yields. The resulting trichloroacetamides were hydrolyzed to the corresponding amines in good yields.
