Title compds. (I, R = Et or CH2CH; R1 = α- or β-anomer of hexopyranose, -furanose, pentopyranose, -furanose, pyranose of furanose amino sugar, di- or trisaccharide residue; R2 = H, alkanoyl, Bz) and their acid addn. salts, useful as agents against g(+), g(-), and anaerobic bacteria, and mycoplasma, were prepd. Thus, 2,3,4,6-tetra-0-benzyl-α-D-glucose was chlorinated with SOCl2 and the product was treated with pleuromutilin in CH2Cl2 in the presence of Et4NBr and (Me2CH) 2NET to give 11.167% 14 - deoxy - 14 -≮2 , 3 , 4 , 6 - tetra - O- benzyl - α - D - glucopyranosyl)oxyacetoxy≉mutiline.
