The stereoselective synthesis of Ø‐maltosides by reacting benzoyl‐substituted heterocyclic ketene aminals 1 or 2 with acetylated maltosyl bromide 3 was investigated. Compounds 1 or 2 reacted with 3 in the presence of mercuric cyanide to give O ‐maltosides 4 or 5 with E ‐configuration. While 1 reacted with 3 in the presence of calcium hydride to give O ‐maltosides 6 with Z ‐configuration.
