formaldehyde N,N-dialkylhydrazones to carbohydrate-derived alpha-alkoxyaldehydes takes place under neutral conditions and in the absence of catalysts or promoters to afford the corresponding alpha-hydroxyhydrazones in good to excellent yields and with highly anti diastereoselectivities. Subsequent transformations of the hydrazono group into aldehydes and nitriles following known procedures provide a new entry
