Degradation of Some Octa-O-Benzoylaldobiononitriles: Studies of The Products by NMR Spectroscopy

The Zemplén degradation of 2, 3, 5, 6, 2’, 3’, 4’, 6’-octa-0-benzoylcellobi-ononitrile (1), -lactobiononitrile (2), and -maltobiononitrile (3) was carried out giving a mixture of the four 3-0-(D-hexopyranosyl)-D-arabinoses. Their reduction gave the 3-O-(D-hexopyranosyl)-D-arabinitols, and their benz...

Sumario:The Zemplén degradation of 2, 3, 5, 6, 2’, 3’, 4’, 6’-octa-0-benzoylcellobi-ononitrile (1), -lactobiononitrile (2), and -maltobiononitrile (3) was carried out giving a mixture of the four 3-0-(D-hexopyranosyl)-D-arabinoses. Their reduction gave the 3-O-(D-hexopyranosyl)-D-arabinitols, and their benzoylation gave the 1, 2, 4, 5, 2’, 3’, 4’, 6’-octa-O-benzoyl-(D-hexopyranosyl)-D-arabinitols. Their 1 H and 13 C NMR spectra are described, and their conformations are determined to be planar zig-zag for the acyclic moieties. © 1989, Taylor & Francis Group, LLC. All rights reserved.
