ENANTIOSELECTIVE SYNTHESIS OF 5,6-DIHYDRO-(S)-4-(ETHYLAMINO)-(S)-6-METHYL-4H-THIENO 2,3-B THIOPYRAN-2-SULFONAMIDE 7,7-DIOXIDE AND RELATED COMPOUNDS |
| 摘要 |
A key step in the synthesis of 5,6-dihydro-(S)-4- (ethylamino)-(S)-6-methyl-4H-thieno¢2,3-b!thiopyran-2-sulfonamide 7,7-dioxide (dorzolamide) and related compounds is a Ritter reaction with an unexpected tendency to proceed with retention of chirality.
