Transformation of α-substituted propanols into γ-amino alcohols through nickel-catalyzed amination on the terminal γ-carbon of propanols

Ueno, Satoshi,Usui, Kazumi,Kuwano, Ryoichi

, p. 1303 - 1307 (2011/07/08)

A nickel-phosphine complex was found to be effective as the catalyst for the transformation of alcohols into β-enaminones, which was successively converted into γ-amino alcohols by a conventional reductant. The sequential transformation is equivalent to the carbon-nitrogen bond formation at the γ-position of saturated alcohols. Georg Thieme Verlag Stuttgart · New York.
