A convenient and efficient one-pot synthesis of N-alkoxymethyl derivatives of secondary amides, sulfonamides and phosphamides in reaction with the appropriate dialkoxymethanes in the presence of a Lewisacid is described. In this method the use of toxic and carcinogenic chloromethyl alkyl ethers was eliminated.
