The Name is 3,5-Dimethyl-1H-pyrazole. Through research, I have a further understanding and discovery of 67-51-6. Product Details of 67-51-6
An efficient and straightforward method for the synthesis of new and versatile sulfonyl-functionalized allylic amines through the selective copper-catalyzed aza-1,6-conjugate addition of heterocycles or arylamines to 1,4-disubstituted-1,3-dienyl sulfones has been developed. This catalytic process is promoted by a combination of an easily prepared and sterically demanding N-heterocyclic carbene-based copper complex and KOt-Bu under mild reaction conditions to provide a broad range of (E)-allylic amines with excellent regio- and stereoselectivities.
