Efficient Total Synthesis of (–)-(3S,6R)-3,6-Dihydroxy-10-methylundecanoic Acid

Enantioselective synthesis of (+)-brevipolide H

The enantioselective synthesis of natural brevipolide H is reported for the first time. By way of Sharpless epoxidation of penta-1,4-dien-3-ol, both enantiomerically pure epoxides were converted to the corresponding olefins for cross metathesis. Subsequent transformations, including epoxide ring opening, esterifications, cyclopropanation, oxidation and ring-closing metathesis, provided the target molecule. This synthesis successfully addresses previous shortcomings in preparing brevipolides.

Two novel 3D lanthanide supramolecular coordination polymers constructed from paddle wheel SBUs and hydrogen bonding: synthesis, structures and properties

Two novel 3D lanthanide supramolecular coordination polymers with lanthanide paddle wheel SBUs were synthesized through in situ generation of formate anions. Their structure and temperature dependent luminescent property are investigated.
