1.  1-O-Acetyl-3,4,6-tri-O-benzyl-2-C-bromo­methyl-2-de­oxy-α-d-glucopyran­ose 
In the title compound, C30H33BrO6, the pyran­ose ring adopts a chair conformation. Two of the O-benzyl phenyl rings lie almost perpendicular to C/C/C/O plane formed by the ring atoms not attached to these O-benzyl phenyl rings, and form dihedral angles of 85.1 (2) and 64.6 (2)°, while the third O-benzyl phenyl ring is twisted so that it makes a dihedral angle 34.9 (2)° to this C/C/C/O plane. This twist is ascribed to the formation of an S(8) loop stabilized by a weak intra­molecular C—H⋯O hydrogen bond.

2.  3,4,6-Tri-O-acetyl-1,2-[(S)-ethyl­idene]-β-d-mannopyran­ose 
In the title compound, C14H20O9, the six-membered pyran and the five-membered dioxalane rings adopt chair and twisted conformations, respectively. In the crystal, the mol­ecules are linked by C—H⋯O inter­actions.

3.  Okundoperoxide, A Bicyclic Cyclofarnesylsesquiterpene Endoperoxide from Scleria striatinux with Antiplasmodial Activity 
Journal of natural products  2009;72(2):280-283.
Okundoperoxide (1) was isolated by bioassay-guided fractionation of extracts from Scleria striatinux (syn. S. striatonux) (Cyperaceae). The compound contains a cyclic endoperoxide structural moiety and possesses moderate antimalarial activity.
