Role of Prins Reaction and Aminomethylation in the Synthesis of 1,3-Oxazinane from α-Methylstyrene

Resumo

Study of the mechanism of formation of 1,3-oxazinane in the reaction of α-methylstyrene with formaldehyde and amines in aqueous medium has shown that 3,6-dimethyl-6-phenyl-1,3-oxazinane is formed as a result of transformations of 4-methyl-4-phenyl-1,3-dioxane which is the Prins reaction product.
