A model study of epothilone synthesis: an alternative synthetic approach to the C1C7 fragment [PDF]
Journal of the Serbian Chemical Society, 2002 In this model study an alternative synthetic approach to the C1C7 fragment of epothilones was investigated. Starting from 4,4-dimethylcyclopentenone, a 7 step reaction sequence afforded the key intermediate 7 in 27 % overall yield.

(NHC)Mn(I) complex catalyzed selective transfer hydrogenation of epoxides, azoarenes and nitroarenes utilizing ammonia borane [PDF]
Herein, we have reported an effective protocol for the regioselective transfer hydrogenation (TH) of epoxides by utilizing a phosphine-free bis-NHC-Mn(I) complex and ammonia borane. By employing this strategy, aromatic epoxides were selectively converted

Cloning and application of epoxide hydrolases from yeasts [PDF]
, 2002 Epoxides are cyclic ethers that readily react with various nucleophilic compounds. Consequently, epoxides can be used in many chemical synthesis reactions. Two enantiomeric forms of an epoxide are possible if one of the carbon atoms is chiral. This means
