Coniselin, a new natural compound, was isolated from the roots of Coniselium Vaginatum Thell.Its structure was elucidated by means of spectroscopic analysis (UV, IR, MS, NMR, DEPT) and confirmed by total synthesis.
The repeat unit of Candida kefyr IFO 0586 strain was designed, and a protected pentasaccharide was synthesized by thirteen-step reactions. Trichloroacetoxy was used as leaving group at anomeric carbon.
