Abstract

Notes ri~ atives.~ These results would suggest that those derivatives may undergo hydrolysis by competitive mechanisms, giving dioxane by an 0-6 process. It is possible that some 3-OH formed via attack by water at one of the methylene carbons of the cyclic oxonium ion. In theory our NM'R experiment with 3-d2-OTs could reveal whether this occurs since the two methylene carbons are not equivalent in the deuterium-labeled tosylate. However, the ...
