Title:
PSICOFURANOSE AND PSICOPYRANOSE DERIVATIVES
Document Type and Number:
WIPO Patent Application WO/1994/013685
Kind Code:
A1
Abstract:
D-psicofuranose and D-psicopyranose derivatives represented by general formulae (I) and (II), useful as the key intermediates in a novel process for producing hydantocidin; wherein R1 through R8 may be the same or different from one another and each represents hydrogen or a hydroxyl-protecting group; and X represents optionally protected hydroxymethyl, carboxyl, carbamoyl or allophanoyl.
