Tetrathiomolybdate has been used as an efficient sulfur-transfer reagent in the synthesis of a number of thiolevomannosan derivatives having an axial-rich C-1(4) conformation. An unprecedented synthesis of a novel thioorthoester and its synthetic utility in glycosylation has been demonstrated. This is a general and efficient method for the synthesis of conformationally locked thiosugars. (c) 2006 Elsevier Ltd. All rights reserved.
