For preparation of a reagent for the high-yield reduction of esters to aldehydes, see Sodium bis(2-methoxyethoxy)-aluminum hydride. Similarly, addition of the hydrochloride to Lithium aluminum hydride, gives a complex which can reduce carboxylic acids to aldehydes: J. Org. Chem., 49, 2279 (1984). The N-lithio-derivative effects the O-alkyl cleavage of aromatic ortho-alkoxyaldehydes or ketones, without the need for carbonyl protection: Synth. Commun., 18, 191 (1988).
