Structural, vibrational, electronic, NMR, NLO and reactivity analyses of (3Z)-3-(2-oxo-2-phenylethylidene)-1,3-dihydro-2H-indol-2-one (OPEDI) by ab initio HF and DFT calculations

This study represents the vibrational, electronic, NMR, NLO, reactivity and structural aspects of (3Z)-3-(2-oxo-2-phenylethylidene)-1,3-dihydro-2H-indol-2- one (OPEDI). A detailed interpretation of the FT-IR, FT-Raman, UV and NMR spectra were reported. Th

Asymmetric Synthesis of Spirooxindoles with Seven Stereocenters via Organocatalyzed One-pot Three-component Sequential Cascade Reactions

A bifunctional squaramide-catalyzed one-pot three-component Michael/Mannich-Michael/cyclization sequential cascade reaction for the construction of bispirooxindole-spirooxindoles was developed in good yields with excellent stereoselectivities (up to >20:1 dr, 99% ee). A series of original cinnamoyl-3-ylideneoxindoles have been applied to this sequential cascade strategy for the first time. This new strategy provides a process for the enantioselective construction of bispirooxindole-spirooxindoles with seven stereocenters, of which three are quaternary spiro-stereocenters. (Figure presented.).

Important properties of sulfur-bonded organoboron (III) complexes with biologically potent ligands

Important properties of sulfur/oxygen and nitrogen bonded organoboron (III) complexes with biologically potent ligands viz., semicarbazone, thiosemicarbazone, and dithiocarbazate having the donor groups ONX and NS have been studied. The unimolar and bimol

Synthesis of Annulated Carbazoles from Indol-2,3-dione

Reaction of ethyl chloroformate with 3-aroylmethylindol-2(3H)-ones 5 affords the ethyl 3--2-(ethoxycarbonyloxy)indole-1-carboxylates 6 from which the corresponding annulated carbazoles 10 are obtained via 6?-electro

Lewis acid-promoted synthesis of highly substituted pyrrole-fused benzoxazinones and quinoxalinones

A synthesis of a series of novel fused tricyclic heterocyclic compounds has been achieved in one-pot reaction set up starting from (E)-3-(2-oxo-2-phenylethylidene)indolin-2-one and 1,4-benzoxazinone/quinoxalinone derivatives promoted by tin(IV) chloride.

Diastereoselective trans Cyclopropanation of 3-Alkylidene Oxindoles with in Situ Generated α-Diazo Carbonyls or α,β-Unsaturated Diazo Compounds

An efficient diastereoselective trans cyclopropanation of 3-alkylidene oxindoles with in situ generated α-diazo carbonyl compounds or α,β-unsaturated diazo compounds under metal-free conditions has been developed to synthesize 3-spirocyclopropyl-2-oxindol

Dynamic Kinetic Asymmetric Transformation of Racemic Diastereomers: Diastereo- and Enantioconvergent Michael–Henry Reactions to Afford Spirooxindoles Bearing Furan-Fused Rings

Dynamic kinetic asymmetric transformation (DYKAT) reactions of racemic diastereomer mixtures that afford the products as essentially single diastereomers with high enantioselectivities are described. We demonstrated the DYKAT in the diastereo- and enantio

Synthesis and evaluation of isatin derivatives as antifungal agents

Various types of isatin derivatives were synthesized by reacting isatin with different reagents viz substituted acetophenones, sodium nitrate, hydroxylamine hydrochloride and hydrazine hydrate. Characterization of the synthesized compounds was done by using various spectral techniques such as IR,1HNMR,13CNMR, elemental analysis and mass spectrometry. Synthesized compounds were further evaluated for their antifungal activity against Helminthosporium oryzae, Rhizoctonia solani and Fusarium moniliforme using poison food technique. 3-(2-Oxo-2-phenylethylidene) indolin-2-one showed significant mycelium inhibition against all tested rice fungi.
