Synthesis of N-Benzylideneaniline by Schiff base reaction using Kinnow peel powder as Green catalyst and comparative study of derivatives through ANOVA techniques. Sci Rep 2022; 12:9636. [PMID: 35688886 PMCID: PMC9187627 DOI: 10.1038/s41598-022-13360-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 05/10/2022] [Indexed: 11/08/2022] Open
Abstract
The cheap and easy availability of the Kinnow peel waste has reported various applications due to presence of multifunctional groups. Therefore, in present study we explored its application to synthesize N-Benzylideneaniline and its derivatives based on Schiff base reaction. Kinnow peel powder is characterized by FTIR, TEM, SEM, XRD, EDX, and TGA for functional groups, morphology, surface, elements and thermal stability. Benzaldehyde, aniline, and their derivatives such as 4-methyl benzaldehyde, 4-hydroxy benzaldehyde, 4-methoxy benzaldehyde, and 4-methoxy aniline have been used to compare the efficacy of the Schiff base reaction using analysis of variance (ANOVA) and it has been observed that combination of Aniline and benzaldehyde for Schiff base reaction provided 85% yield of relative product.

Abstract
Cashew Nut Shell Liquid (CNSL) anacardic acid was used, for the first time, as a green and natural effective catalyst for the synthesis of a quinoline based amino acid Schiff base ligand from the condensation of 2-hydroxyquinoline-3-carbaldehyde with l-tryptophan via solvent-free simple physical grinding technique. The use of the nontoxic CNSL natural catalyst has many benefits over toxic reagents and the desired product was obtained in high yield in a short reaction time. The procedure employed is simple and does not involve column chromatography. Moreover, a series of metal(II) complexes (metal = iron(II), cobalt(II), nickel(II), and copper(II)) supported by the synthesized new quinoline based amino acid Schiff base ligand (L) has been designed and the compositions of the metal(II) complexes were examined by various analytical techniques. The findings imply that the 2-hydroxyquinoline-3-carbaldehyde amino acid Schiff base (L) serves as a dibasic tridentate ONO ligand and synchronizes with the metal(II) in octahedral geometry in accordance with the general formula [M(LH)2]. Molecular docking study of the metal(II) complexes with B-DNA dodecamer has revealed good binding energy. The conductivity parameters in DMSO suggest the existence of nonelectrolyte species. The interaction of these metal complexes with CT-DNA has shown strong binding via an intercalative mode with a different pattern of DNA binding, while UV-visible photo-induced molecular cleavage analysis against plasmid DNA using agarose gel electrophoresis has revealed that the metal complexes exhibit photo induced nuclease activity.

Abstract
A waste feedstock-derived economical basic alternative catalyst is described in this review. Eggshell is one of the household wastes created in tons of weight daily. Therefore, in order to reduce the environmental pollution-related problems, its use in heterogeneous catalysis can be attributed as a great contribution for the chemical and material science society to carry out several known reactions and for the much-needed energy alternative biodiesel production as low-cost catalytic system. Keeping green chemistry in mind, industrial use of these catalysts may also reduce the use of other traditionally used high-cost chemical catalytic systems.

Abstract
Green chemical one-pot multicomponent condensation reaction of substituted 1H-indole-2,3-diones (1), various amino acids (2), and thiosemicarbazide (3) is found to be catalyzed by lemon juice as natural acid using water as a green solvent to give the corresponding Schiff bases (4) in good to excellent yields. This method is experimentally simple, clean, high yielding, and green, with reduced reaction times. The product is purified by simple filtration followed by washing with water and drying process. The synthesized compounds are characterized by FT-IR,13CNMR, and1HNMR spectroscopy and are screened for their antifungal activity againstAspergillus niger,Penicillium notatum,Fusarium oxysporum,Alternaria brassicicola,Chaetomium orium, andLycopodium sp.and antibacterial activity against Gram-positive bacteria,Bacillus licheniformis,Staphylococcus aureus, andMicrococcus luteus,and Gram-negative bacteria,Pseudomonas aeruginosaandEscherichia coli. Compounds have also been evaluated for cytotoxic effects against human colon cancer cell line Colo205.
