N,N,N′,N′-Tetramethylazodicarboxamide, TMAD, was found to be more versatile in the Mitsunobu reaction than traditional diethyl azodicarboxylate or recently developed 1,1′-(azodicarbonyl)dipiperidine, when used in combination with tributylphosphine in benzene. The usefulness of the reagent was demonstrated by the highly efficient two-step synthesis of benzylcrotylamine from N-benzyltrifluoroacetamide
N,N,N',N'-四甲基偶氮二甲酰胺,TMAD,当与苯中的三丁基膦结合使用时,比传统的偶氮二甲酸二乙酯或最近开发的 1,1'-(偶氮二羰基)二哌啶在光信反应中更通用。从 N-苄基三氟乙酰胺高效两步合成苄基巴豆胺证明了该试剂的有用性。
