Commun. , : 578 Sharpless epoxidation of 1a, using either the catalytic or stoichiometric procedure, was unsuccessful and could not be improved by using a more acid stable acetal, such as a 5,5-dimethyl-1,3-dioxane. The lability of 1,3-dioxolanes toward Sharpless epoxidations have been observed previously:
