  Flexible Protocol for the Chemo- and Regioselective Building of Pyrroles and Pyrazoles by Reactions of Danishefsky’s Dienes with 1,2-Diaza-1,3-butadienes

  摘要：

  The versatility of the Mukaiyama-Michael-type addition/heterocyclization of Danishefsky's diene with 1,2-diaza-1,3-butadienes was applied to the synthesis of both 4H-1-aminopyrroles and 4,5H-pyrazoles. Thus, the same reagents furnished different types of highly functionalized azaheterocycles essentially depending on their structure: as a matter of fact, R-1 = COOR or CONR2 differently affects the acidity of the proton at the adjacent carbon. An unexpected formation of 5H-1-aminopyrroles from the reactions carried out in water was also observed.
