Optically active sugar thioamides from δ-gluconolactone
摘要:
This paper describes a facile and rapid approach to N-alkyl- and N-aryl-thiogluconamides employing delta-gluconolactone as starting material. The protocol involves a three-step sequence to afford the corresponding thioamides as crystalline substances in moderate to good yields. The Lawesson reagent was found to be the reagent of choice to accomplish the key transformation amide-thioamide. (C) 2000 Elsevier Science Ltd. All rights reserved.

Ice recrystallization inhibitor (IRI) compounds and methods for cryopreserving umbilical cord blood are provided. The compounds are unsubstituted, mono-substituted, or di-substituted aryl-aldonamides. The methods include fractionating whole umbilical cord blood to generate a fraction comprising hematopoietic stem cells, mixing the hematopoietic stem cells with at least one IRI compound to form an IRI suspension, and freezing the IRI suspension.
