Rhodanine derivatives, specially arylidenerhodanines, have proven a wide array of pharmacological routines, which involve anticonvulsant, antibacterial, antiviral, and antidiabetic effects [1�C3]. Arylidenerhodanines are typically ready by reacting aldehydes and rhodanine in natural solvents and while in the presence of organic bases like piperidine [2, 4�C8].
A short while ago, catalysts such as 2,two,six,6-tetramethyl piperidine [9, 10], NH4Cl/NH4OH , K2CO3/[bmim]BF4/H2O , NaOAc/HOAc [3, 13, 14], glycine , ammonium acetate [16, 17], 1-butyl-3-methyl imidazolium hydroxide [18, 19], tetrabutylammonium bromide , and K2CO3/Al2O3  have already been applied within this reaction.
While these solutions are worthwhile, nearly all of them have problems with some drawbacks this kind of as a lengthy response time, low yields, using toxic solvent, costly catalyst, requiring a promoter, this kind of as microwave, and tedious work-up procedures. So, the advancement of the new process for that synthesis of arylidenerhodanines can be extremely desirable.Water is abundant, reasonably priced, safe, andselleck chemical BIIB021 clean. Among various solvents, water will be the most favored solvent. Using water as a solvent is the technique normally employed towards greener chemistry. A wide choice of reactions that can be performed in or on water are already created [22�C24].
Diammonium hydrogen phosphate has become made use of as an productive, nontoxic, and affordable catalyst in natural synthesis [25�C28]. Like a part of our endeavors in the direction of the development of productive, and environmentally benign synthetic methodologies in water [29�C32], we report herein an easy, productive, and useful process to the synthesis of 5-arylidenerhodanines by the condensation of rhodanine with aromatic aldehydes from the presence of diammonium hydrogen phosphate in water (Scheme 1).Scheme 1Diammonium hydrogen phosphate catalyzed synthesis of 5-arylidenerhodanines.2.
