Heat pyrolysis of the oxazines formed from 2-piperidineethanol produced 2,3-dehydropiperidine enamines. The same results were observed when these oxazines were irradiated with microwaves. Various 2-substituted perhydrooxazines were synthesized by allowing 2-piperidineethanol or 2-piperidinemethanol to react with aldehydes or ketones.

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.

Several novel 1,3-oxazinane and oxazolidine derivatives were obtained from the corresponding N-benzyl-2-(2-hydroxyethyl)-and N-benzyl-2-(hydroxymethyl) piperidines via electrochemical oxidation. The reactions were carried out in methanol under basic conditions. The yields of the cyclic products were significantly improved using catalytic amounts of iodide ions, which presumably act as effective electron carriers in the two-electron oxidation process.
