Several novel 2-aryl-1,3-oxazinane and 2-aryl-1,3-oxazolidine derivatives were synthesized from N-benzyl-2-piperidineethanols and N-benzyl-2- piperidinemethanols, respectively, by using electrooxidative methods in methanol. For these reactions, the yields of the corresponding cyclized compounds were significantly increased by using catalytic amounts of iodide ions. In contrast, 3-dialkylamino-1-phenylpropanols afforded the expected cyclic 6-phenyl-1,3-oxazinane derivatives using only a small excess of base. Georg Thieme Verlag Stuttgart · New York.

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.
Intramolecular Quenching of Iminium Ions Generated by Photooxidation of Aminoalcohols with Ketones. A New Synthesis of Oxazines and Oxazoles
Cossy, Janine,Guha, Madhumita
, p. 1715 - 1718 (2007/10/02)
The irradiation of tertiary amines in the presence of ketones leads to a regioselective and stereoselective formation of iminium salts which then react to afford the corresponding oxazines or oxazoles. - Key words : Ammoniumyl ions, iminium ions, electron transfer, amines, ketones, tetrahydrooxazine tetrahydrooxazoles.
