Amination of allylicalcohols is facilitated via cooperative catalysis. Catalytic Ti(O-i-Pr)4 is shown to dramatically increase the rate of nickel-catalyzed allylic amination, and mechanistic experiments confirm activation of the allylicalcohol by titanium. Aminations of primary and secondary allylicalcohols are demonstrated with a variety of amine nucleophiles. Diene-containing substrates also cyclize

A process is described for the preparation of 3-(5-formyl-2-hydroxyphenyl)-3-phenylpropylamine derivatives, intermediates which can be used for preparation of agents for urinary incontinence therapy, specifically to 2-(3-(diisopropylamino)-1-phenylpropyl)-4-(hydroxymethyl)phenol and its prodrugs.
The direct electrophilic, nucleophilic, and amphiphilic allylations of allylic alcohol by use of a palladium catalyst and organometallic reagents such as organoborane and organozinc has been developed. The phosphine–borane compound works as the effective ligand for palladium-catalyzed direct allylic amination of allylic alcohol. Thus, with secondary amines, the reaction was completed in only 1 h, even
