Study of Influence on Mesomorphic Properties by Structural Changes with Additional -CH2-CH2- Spacer between Two Rigid Cores

Umed C. Bhoya, Mukesh R. Dube, Mona B. Pithiya

World Scientific News > 2022 > 164 > 64-76

The novel poly mesomorphic homologous series was synthesized to understand the mesomorphic behaviour of compounds with respect to molecular structure. Present series was consisting 11 homologues which were completely smectogenic and along with poly-mesomorphism. In smectogenic texture it shows some broken fane like texture which represent the presence of smectic-A texture along with smectic-C. Mesomorphic...

Synthesis, Characteristics and Application of Nanoferite Catalyst for the Oxidation of Methylene Blue Dye in Aqueous Medium

Kalpesh R. Kholiya, Ravi M. Hirani, Umed C Bhoya

World Scientific News > 2022 > 167 > 145-161

The Fenton degradation is an effective oxidation reaction used for degradation of harmful organic substances in waste water. The Fenton degradation reaction has a wide application in industrial waste water treatment because industrial waste water contains different types of toxic organic compounds which are harmful to environment. The present study gives advanced application of Fenton like degradation...

The mesomorphic effect of –CH2-CH2- spacer on thiophene chalconyl ester containing compounds

Umed C. Bhoya, Mona B. Pithiya, Mukesh R. Dube, Kalpesh R. Kholiya

World Scientific News > 2022 > 169 > 183-201

A new thiophene ring containing chalconyl ester homologous series was synthesised with ethyl spacer to understand the effect of structural change on mesomorphism. This homologous series was compared with well reported similar homologous series to evaluate the liquid crystal properties after addition of ethyl spacer. This series contain 12 homologues. Among 12 homologues C10 to C16 homologues show...

Molecular Structural Flexibility Dependence of Mesomorphism through Ortho–Substituted Nitro Group

Sagarkumar U. Ravalia, Mukesh R. Dube, Umed C. Bhoya

World Scientific News > 2021 > 159 > 59-70

A novel homologous series of liquid crystalline materials of schiff’s bases viz. RO-C6H4-CH=CH-COO-C6H4-N=CH-C6H4-NO2 is synthesized and studied with a view to understanding and establishing the effect of molecular structure on liquid crystal properties and to provide novel thermotropic LC material to the scientific and technological community of research interest. The novel series consist of 12 homologues...

Synthesis and pharmacokinetic study of new thiazole derivatives containing pyrazole moiety

Dipti L. Namera, Umed C. Bhoya, Anamik K. Shah

World Scientific News > 2019 > 132 > 277-284

For developed new eco-friendly synthetic route for the synthesis of organic compounds, here in, we have synthesized new series of thiazole derivatives 7(a-h) under microwave irradiation method using less amount of methanol as solvent and less hazardous K2CO3 as catalyst. Then after for the pharmacokinetic study, we can calculate Lipinski rules of five data using swiss ADME software, molecule 7f was...

Remote Amide‐Controlled Gold‐Catalyzed Stereoselective Hydro‐heteroarylation of Acrylamides: Access to Pyrido[3,4‐b]indoles

Himanshu H. Butani, Dipak D. Vachhani, Umed C. Bhoya, Anamik K. Shah, more

European Journal of Organic Chemistry > 2015 > 10 > 2124 - 2128

The amide functionality was used as a remote control for the stereoselective hydro‐heteroarylation of acrylamides. This gold‐catalyzed carbocyclization provides a diversity‐oriented and concise route to biologically important pyrido[3,4‐b]indoles. Moreover, the adverse effect of silver salts on this hydro‐heteroarylation was also studied.

Regio‐ and Chemoselective Formation of Spiroindolinone–Isoindolinone by a Palladium‐Catalyzed Buchwald–Hartwig Addition–Elimination Sequence

Himanshu H. Butani, Dipak D. Vachhani, Umed C. Bhoya, Anamik K. Shah, more

European Journal of Organic Chemistry > 2014 > 30 > 6634 - 6638

The usual way to synthesize spiroindolinones is the application of isatin derivatives. Here, we report the first Pd‐catalyzed Buchwald–Hartwig addition–elimination strategy for the formation of the spiroindolinone–isoindolinone architecture. The application of the Ugi‐4‐component reaction (Ugi‐4CR) allows the facile introduction of diversity and increases the practicality of this protocol.
