摘要:
This invention concerns the short synthesis of 5,6-dihydro-(S)-4-(ethylamino)-(S)-6-[C.sup.3 H.sub.3 ]-4H-thieno [2,3-b]thiopyran-2-sulfonamide 7,7-dioxide and related non-radioactive and radioactive compounds. The key step is the regioselective and stereo-controlled methylation of the C-6 (.alpha.-sulfone) carbanion in the presence of the monoprotected sulfonamide anion.
