The thioalkylation of unprotected 5-bromo-5-deoxy-D-ribono, D-arabinono, and D-xylono-1,4-lactone was performed with the alkylthiol-sodium hydride reagent. The corresponding 5-S-alkyl-5-thio-D-pentono-1,4-lactones were isolated in good yields (82-95%). Reduction with NaBH4 of these derivatives gave the 1-S-alkyl-1-thio-L-ribitols, D-lyxitols and L-xylitols in 85-96% yields. (C) 2001 Elsevier Science Ltd. All rights reserved.
