Use of 1-methoxy-1-trimethylsilylallene oxide and titanium tetraiodide as a dianion synthon of methoxyacetone
A dianion equivalent of methoxyacetone was successfully generated using 1-methoxy-1-trimethylsilylallene oxide and titanium tetraiodide and subsequent reaction with acetals or aldehydes gave alpha -methoxy-alpha,beta -unsaturated ketones in good yields.
