The reaction of protected glucuronic esters 2 and 7, as well as D-glucuronolactone derivative 11, with (trimethylsilyl)methylmagnesium chloride in ether led to the corresponding stable bis-silyl adducts 3, 8, and 12, respectively. In Peterson-type reactions catalysed with mild acid, these compounds
