A concise synthesis of the HCV protease inhibitor BILN 2061 and its P3 modified analogs

A concise synthesis of BILN 2061 was achieved through more efficient installation of P2 4-quinoline moiety via SN2 displacement of the β-OBs group located on the 4-hydroxyl proline intermediate, which was prepared from 4-α-hydroxyl proline analog via Mitsunobu reaction with inversion of stereochemistry. In addition, a short and practical synthesis for P3 unit is also described herein. Final assembly of four fragments for BILN 2061 was achieved with an overall yield of 58% in 4 steps from P1 to 15a. Furthermore several analogs of BILN 2061 (WX-1-WX-5) containing modifications on P3 unit were synthesized successfully using the same synthetic route as described for the parent inhibitor BILN 2061.
