Synthesis of Nitriles from Aldoximes and Primary Amides Using XtalFluor-E
The dehydration reaction of aldoximes and amides for the synthesis of nitriles using [Et2NSF2]BF4 (XtalFluor-E) is described. Overall, the reaction proceeds rapidly (normally 1 h) at room temperature in an environmentally benign solvent (EtOAc) with only a slight excess of the dehydrating agent (1.1 equiv). A broad scope of nitriles can be prepared, including chiral nonracemic ones. In addition, in a number of cases, further purification of the nitrile after the workup was not required.

Nitrilase-catalyzed enantioselective synthesis of pyrrolidine- And piperidinecarboxylic acids
The enantioselective synthesis of the nonproteinogenic amino acids β-proline and nipecotic acids from their readily available nitriles is achieved in high enantiomeric excess by commercially available nitrilases. The presented procedure comprises not more than 4 steps, thus considerably reducing the multiple steps generally required. Amide formation is also observed for specific heterocyclic nitriles.

PROLINE DERIVATIVES AND USE THEREOF AS DRUGS
The present invention aims at providing compounds having therapeutic effects due to a DPP-IV inhibitory action, and satisfactory as pharmaceutical products. The present inventors have found that derivatives having a substituent introduced into the γ-position of proline represented by the formula (I) wherein each symbol is as defined in the specification, have a potent DPP-IV inhibitory activity, and completed the present invention by increasing the stability.
