Results The successful synthetic route is based on Majumdar's observation of the stability of (dialky1amino) methaneboronic esters5 and his efficient new synthesis of a-chloro boronic ester^,^ as well as his observation of SN2 displacement on an a-chloro boronic ester by a highly hindered dialkylamide.'O Thus, ethylene glycol benzylboronate (la) with (dich10romethyl) lithium~ yielded ethylene glycol 1-chloro-2-phenylethane-1-boronate ( ...
