Bogdanov, Andrei V. published the artcileNew N-Mannich bases obtained from isatin and piperazine derivatives: the synthesis and evaluation of antimicrobial activity, Related Products of piperazines, the publication is Chemistry of Heterocyclic Compounds (New York, NY, United States) (2016), 52(1), 25-30, database is CAplus.
A Mannich reaction of isatin with monosubstituted piperazines in the presence of aqueous formaldehyde was used to synthesize new, as well as two previously described derivatives of 1-[(piperazinyl)methyl]isatins, which were further converted to isoindigo derivatives The antimicrobial activity of the obtained heterocycles was evaluated.
Chemistry of Heterocyclic Compounds (New York, NY, United States) published new progress about 87179-40-6. 87179-40-6 belongs to piperazines, auxiliary class Benzenes, name is (E)-1-Cinnamylpiperazine, and the molecular formula is C13H18N2, Related Products of piperazines.
