Protic ionic liquid [TMG][Ac] as an efficient, homogeneous and recyclable catalyst for one-pot four-component synthesis of 2H-indazolo[2,1-b]phthalazine-triones and dihydro-1H-pyrano[2,3-c]pyrazol-6-ones

The mildly basic ionic liquid N,N,N,N-tetramethylguanidinium acetate [TMG][Ac] was found to be a very effective basic catalyst for the one-pot, four-component synthesis of 2H-indazolo[2,1-b] phthalazinetriones by condensation of phthalic anhydride, hydrazinium hydroxide, aromatic aldehydes, and dimedone in high yields at 80 degrees C. [TMG][Ac] catalyzed simple and efficient one-pot four-component reaction of Meldrums acid, ethyl acetoacetate, hydrazine hydrate, and aromatic aldehydes to give dihydro-1H-pyrano[2,3-c] pyrazol-6-ones is reported. The ionic liquid could be recycled several times without loss of efficiency with regards to the reaction times and yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 502496-34-6. COA of Formula: C7H5BrFNO2.

Synthesis and evaluation of new phthalazine substituted beta-lactam derivatives as carbonic anhydrase inhibitors

A new series of phthalazine substituted beta-lactam derivatives were synthesized and their inhibitory effects on the activity of purified human carbonic anhydrase (hCA I and II) were evaluated. 2H-Indazolo[2,1-b]phthalazine-trione derivative was prepared with 4-nitrobenzaldehyde, dimedone, and phthalhydrazide in the presence of TFA in DMF, and the nitro group was reduced to 13-(4-aminophenyl)-3,3-dimethyl-3,4-dihydro-2H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione with SnCl2 center dot 2H(2)O. The reduced compound was reacted with different aromatic aldehydes, and phthalazine substituted imines were synthesized. The imine compounds undergo (2+2) cycloaddition reactions with ketenes to produce 2H-indazolo[2,1-b]phthalazine-trione substituted beta-lactam derivatives. The beta-lactam compounds were tested as inhibitors of the CA isoenzyme activity. The results showed that all the synthesized compounds inhibited the CA isoenzyme activity. 1-(4-(3,3-dimethyl-1,6,11-trioxo-2,3,4,6,11,13-hexahydro-1H-indazolo[1,2b]phthalazin-13-yl)phenyl)-2-oxo-4-p-tolylazetidin-3-yl acetate (IC50 = 6.97 A mu M for hCA I and 8.48 A mu M for hCA II) had the most inhibitory effect.

An improved procedure for the three-component synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives using basic ionic liquid

An efficient and green method for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been achieved through the one-pot, three-component condensation of aromatic aldehydes, malononitrile or ethyl cyanoacetate, and phthalhydrazide in the presence of 1-butyl-3-methyl imidazolium hydroxide ([bmim]OH) as catalyst in EtOH. This reaction does not involve any hazardous organic solvent and toxic catalyst. The ionic liquid can be recovered and recycled for subsequent reactions. Moreover, this protocol has the advantages of easy work-up, short reaction time, mild reaction conditions and environmentally benign procedures compared with the reported methods.

Ruthenium Catalyzed C-H Amidation and Carbocyclization using Isocyanates: An Access to Amidated 2-phenylphthalazine-1,4-diones and Indazolo[1,2-b]phthalazine-triones

A direct carbocyclization of 2-aryl-2,3-dihydrophthalazine-1,4-diones is achieved using isocyanates as carbonyl source via Ru(II)-catalyzed sequential ortho-amidation followed by intramolecular nucleophilic substitution, delivering substituted indazolo[1,2-b]phthalazine-triones in good-to-excellent yields. For ortho-substituted 2-aryl-2,3-dihydrophthalazine-1,4-diones, the corresponding amidated products were also isolated in excellent yields by modifying the reaction parameters. Application of isocyanates as carbonyl source, high functional group tolerance on the two coupling partners and diverse chemical transformation of the synthesized fused and functionalized phthalazinones are the key highlights of the work.
