The methodology to prepare 3-substituted 1,5-dibromopentanes I and their immediate precursors, which include 3-substituted 1,5-pentanediols VII or 4-substituted tetrahydropyrans VIII, is surveyed. Such dibromides I are important intermediates in the preparation of liquid crystalline derivatives containing 6-membered heterocyclic rings. Four

Syntheses are described for penicillins (4b approximately 4i, 5a and 5b) which possess a 6 beta-(2-heteroaryl-3-substituted)-propenamido side-chain of fixed geometry. In vitro results for these compounds against a range of Gram-positive and Gram-negative bacteria showed in most cases good stability

As the first example for the synthesis of optically active alpha-hydroxyaldehydes and alpha-hydroxyketones in ionic liquids, we applied RTILs into L-proline catalyzed direct enantioselective alpha-aminoxylation of both aldehydes and ketones successfully. This protocol features a number of advantages, such as
