A convenient, novel synthesis of β-ketosilanes based on (Z)-1-bromo-1-alkenylboronate esters is developed. α-Bromo-(Z)-1-alkenylboronate esters readily available using literature procedures smoothly undergo a reaction with trimethylsilylmethyllithium in tetrahydrofuran to provide the corresponding ‘ate’ complexes. These ‘ate’ complexes will undergo intramolecular nucleophilic substitution reactions
