SYNTHESES OF (PSEUD)___--α-D-ARABINOFURANOSE, (PSEUDO)___--β-D-ARABINOFURANOSE, AND (PSEUDO)___--β-L-XYLOFURANOSE, THREE OPTICALLY ACTIVE (PSEUDO)___--PENTOFURANOSES, FROM D-GLUCOSE

Abstract

Using lead tetraacetate oxidaton and cyclitol formation with KF in the presence of 18-crown-6 as key reactions, three optically active (pseudo)___--pentofuranoses : (pseudo)___--α-D-arabinofuranose, (pseudo)___--β-D-arabinofuranose, and (pseudo)___--β-L-xylofuranose, have been synthesized from D-glucose, (via)___- nitrofuranose derivatives which were common reaction intermediates in previous (pseudo)___--hexopyranose synthesis.
