A-C-glycoside

Nikkomycins. The nikkomycins (141—159), isolated from S. tendae are nucleoside-peptide antibiotics (1,4,244,245) as shown in Table 8. Nikkomycins X and Z are stmcturaHy identical to neopolyoxins A and C, respectively. Compound (141) is a competitive inhibitor of chitin synthetase. Two new nikkomycins, nikkomycin pseudo-Z and pseudo-J (158, 159), contain a C-glycosidic bond between C-5 of uracil and C-1 of... 

When stabilized ylids such as Ph3P=CHC02Et are used, the cyclization of the open chain product to afford a C-glycoside can be effected by a base catalyzed... 

Two new sugars were linked by a C-glycosidic bond p-D-ribopyranoside in Passiflora and p-D-6-deoxygulopyranoside in Viola. A 3,6,8-tri-C-xylosylflavone was isolated from Asplenium. ...
