Abstract
We have established that the recyclization of isocoumarins via 2-hydroxydesoxybenzon-2’-carboxylic acid amides and their subsequent reaction with DMFDMA is an efficient synthetic approach to previously difficult to obtain isoflavones with an amide function. The subsequent recyclization of isoflavones resulted in functionalized pyrazoles with with antibacterial activity.
