SYNTHESIS OF THE DISACCHARIDE C-D FRAGMENT FOUND IN EVERNINOMICIN-C AND -D, AVALAMYCIN-A AND -C, AND CURAMYCIN-A: STEREOCHEMISTRY AT THE SPIRO-ORTHOLACTONE CENTER

Article abstract of DOI:10.1016/S0040-4039(00)95922-7

The two isomers at the spiro-ortholactone center of the disaccharide C-D fragment of orthosomycins have been synthesized.Their mild acidic hydrolysis was under stereoelectronic control with each isomer leading to only one ester.It is therefore possible, f
