  N-Alkylation of α-imino ester derived from ethyl glyoxylate proceeded to give an aluminum enolate that reacted with aldehydes to give 1,2-amino alcohols in good yields. This kind of N-alkylation–addition reaction proceeds efficiently by the use of a new flow system consisting of connected two microreactors.
