J. Mlynarski et A. Banaszek, THE FIRST SYNTHESIS OF THE KETENE DITHIOACETALS FROM SUGAR LACTONES -A CONVENIENT ACCESS TO 3-ULOSONIC ACIDS, Tetrahedron letters, 39(30), 1998, pp. 5425-5428
Isomeric 2-deoxy aldonolactones undergo Horner-Emmons reactions with b
is(2,2,2-trifluoroethoxy)phosphoryl]1,3-dithiane, to give the correspo
nding ketene dithioacetals, which are the key intermediates in the syn
thesis of 3-deoxy-2-keto-aldonic acids. (C) 1998 Published by Elsevier
