  Synthesis of 2,3-Dihydrobenzo[b]thiophen-3-amine 1,1-Dioxide Derivatives via LDA-Mediated Cyclization of o-(Alkylsulfonyl)benzyl Azides with Denitrogenation

  摘要：

  A new and efficient method for the synthesis of 2,3-dihydrobenzo[b]thiophen-3-amine 1,1-dioxide derivatives has been developed. Thus, treatment of o-(alkylsulfonyl)benzyl azides, which are readily obtainable from commercially available starting materials by easily operational sequences, with lithium diisopropylamide (LDA) in THE at -78 degrees C gives, after aqueous workup, 2,3-dihydrobenzo[b]thiophen-3-amine 1,1-dioxides. These products can be isolated in moderate to fair yields after N-protection with acylating agents.

  Rotationally restricted mimics of rigid molecules: nonspirocyclic hydantoin aldose reductase inhibitors

  摘要：

  Sorbinil (1), a spirocyclic hydantoin, is a potent inhibitor of the enzyme aldose reductase. Simulation of the rigid spirocyclic ring orientation found in sorbinil was achieved with nonspirocyclic 5-[5'-chloro-2'-(alkylsulfonyl)-phenyl]hydantoins and 5-[5'-chloro-2'-[(N-alkylamino)sulfonyl]phenyl]hydantoins. The 2'-substituent (SO2R) was sufficiently large to hinder rotation of the hydantoin ring, forcing an orientation similar to that of a spirocyclic hydantoin. Calculated conformational preference, X-ray data, and inhibitory IC50 values for these nonspirocyclic 2'-substituted (SO2R) phenylhydantoins are in accord with what is expected for spirocyclic hydantoins and comparable to those of sorbinil.

• Three-Dimensional Heterocycles by Iron-Catalyzed Ring-Closing Sulfoxide Imidation

  atom‐economical method for the synthesis of cyclic sulfoximines by intramolecular imidations of azido‐containing sulfoxides using a commercially available FeII phthalocyanine (FeIIPc) as catalyst has been developed. The method conveys a broad functional group tolerance and the resulting three‐dimensional heterocycles can be modified by cross‐coupling reactions.
