N2  - Reaction of 2-ethoxy-2-methyl-1,3-dioxolan (1c) with 1-methoxy-1-trimethylsilyloxyethene (4a) in dichloromethane in the presence of titanium tetrachloride gave 62% of methyl 2-(2&#8242;-methyl-1&#8242;,3&#8242;-dioxolan-2&#8242;-yl)acetate (5a). Similarly, reaction of (1c) with l-methoxy-1-trimethylsilyloxyprop-1-ene (4b) afforded 73% of methyl 2-(2&#8242;-methyl-1&#8242;,3&#8242;-dioxolan-2&#8242;-yl) propanoate (5b).
