This manuscript describes a continuous flow protocol for the α-alkylation of esters. The method is based on the generation of lithium enolate intermediates from the esters and in situ delivered LDA. The process is then integrated with the electrophilic addition step and a quench in line. A series of α-functionalized ester have been prepared using this procedure with moderate to good yields.
