  Reactions of per(poly)-fluoroalkanesulfonyl azides with β-ketoester enamines, a new route to N-per(poly) fluoroalkanesulfonyl amidines

  摘要：

  Per(poly)-fluoroalkanesulfonyl azides reacted readily with beta-ketoester enamines to afford good yields of N-per(poly)-fluoro-alkanesulfonyl amidines and diazoacetates. Similarly, treatment of the azides with the cycle analogues ethyl 2-(1-morpholine) 1-cyclopentenecarboxylate gave amidines containing diazo groups. The reaction mechanisms and solvent effects are discussed. (C) 2000 Elsevier Science S.A. All rights reserved.

  In the presence of a secondary amine, treatment of α-keto esters with fluoroalkanesulfonyl azides at room temperature afforded N-sulfonyl protected β-amino-α-keto esters in good to excellent yields. This reaction provided a novel, direct and convenient access to N-sulfonyl protected β-amino-α-keto esters from α-keto esters and fluoroalkanesulfonyl azides under mild conditions. However, the reaction

  在仲胺的存在下，在室温下用氟代链烷磺酰基叠氮化物处理α-酮酯，得到良好收率的N-磺酰基保护的β-氨基-α-酮酯。该反应提供了在温和条件下从α-酮酯和氟代链烷磺酰基叠氮化物获得N-磺酰基保护的β-氨基-α-酮酯的新颖，直接和方便的途径。然而，氟代烷烃磺酰基叠氮化物与β-酮酯烯胺的反应提供了两种产物：N-氟代烷烃磺酰基am和重氮乙酸酯。讨论了反应机理。
