title: A reinvestigation of the synthesis and revision of spectral data of 1,2-O-isopropylidene-α-l-sorbofuranose, 1,2:4,6-di-O-isopropylidene-α-L-sorbofuranose and derivatives.
abstract: Mono- and di-O-isopropylidene-l-sorbofuranose derivatives are important starting materials for the synthesis of modified sugars and useful chiral compounds. However, several inconsistencies in the spectral data of these compounds and erroneous structural assignments have been noted in the literature. The unambiguous synthesis of 1,2:4,6-di-O-isopropylidene-α-L-sorbofuranose and derivatives of 1,2- and 2,3-O-isopropylidene-α-L-sorbofuranoses has been achieved and definitive spectral data on these compounds are provided.
