Studies on the Synthesis of Trisaccharide Analogues of the Antibiotic Moenomycin A

A new approach for the synthesis of moenomycin trisaccharide analogues is reported in which three monosaccharide building blocks are used and allows the introduction of different substituents at the 6‐position of unit E ( Scheme 2 ). Furthermore, a new procedure for the introduction and manipulation of unit F is described ( Scheme 3 ).
