## Abstract A novel method for the synthesis of __N__‐methylserines has been developed. The oxazolidines 4 are formed by condensation of the serine methyl esters 1 with formaldehyde. These intermediates are subsequently reduced to the __N__‐methylserine methyl esters 9 by an acid‐catalyzed ring ope
