PMA/SiO₂ – An efficient recyclable heterogeneous catalyst for the synthesis of homoallyl alcohols and amines under solvent-free conditions

Canadian Journal of Chemistry (2008)

Biswanath Das Rathod Aravind Kumar Ponnaboina Thirupathi Kanaparthy Suneel P. Sunitha

Aldehydes and imines can efficiently undergo nucleophilic addition reaction with allyltributylstannane in the presence of phosphomolybdic acid supported on silica (PMA/SiO 2 ) under solvent free-conditions to form the corresponding homoallyl alcohols and amines respectively at room temperature in excellent yields. The catalyst can be easily recovered and re-used.Key words: homoallyl alcohol, homoallyl amine, phosphomolybdic acid, heterogeneous catalyst, allyltributylstannane, solvent-free conditions.

One-pot multicomponent synthesis of β-acetamidoketones catalysed by pTSA¹

Canadian Journal of Chemistry (2007)

Biswanath Das Kongara Ravinder Reddy Yallamalla Srinivas Rathod Aravind Kumar

A catalytic amount of pTSA has been found to be effective to carry out a one-pot three-component coupling of aromatic aldehydes, enolizable ketones or ketoesters, and acetonitrile in the presence of acetyl chloride to afford β-acetamidoketones in high yields. Short reaction times and inexpensive catalyst are main advantages of this protocol.Key words: β-acetamidoketone, pTSA, multicomponent reaction, diastereoselectivity.

Catalyst-Free Synthesis of Novel 6-Phenyl-6H-chromeno [4, 3-b] quinoline Derivatives at RT: Their Further Structure Evaluation Leads to Potential Anti-cancer Agents

Natural Product Communications (2017)

Alleni Suman Kumar Rathod Aravind Kumar Vavilapally Satyanarayana E. Pravardhan Reddy Boggu Jagan Mohan Reddy

A variety of novel quinoline derivatives (6-phenyl-6 H-chromeno [4,3- b] quinoline) have been prepared by using 4-chloro-2-phenyl-2 H-chromene-3-carbaldehyde and various substituted of aromatic anilines as starting materials. This is the first example on the preparation of quinolines through this novel method. And the resulting quinoline derivatives further structure evolution is leads to an anti cancer agents. Our preliminary data of model compound (7i) on three cancer cell lines (B16F10, MCF7 and A549) suggested decent anticancer activity on two cell lines (B16F10 and MCF7) with IC50 values of 14.8 and 21.32 μM, respectively. This method is operationally simple and works with a diverse range of substrates.

The First Stereoselective Total Synthesis of a Naturally Occurring Bioactive Diarylheptanoid, (3R,6E)‐1,7‐Bis(4‐hydroxyphenyl)hept‐6‐en‐3‐ol, through Two Different Approaches

Helvetica Chimica Acta (2012)

Abstract The stereoselective total synthesis of a naturally occurring bioactive diarylheptanoid, (3 R ,6 E )‐1,7‐bis(4‐hydroxyphenyl)hept‐6‐en‐3‐ol, has been accomplished starting from 4‐hydroxybenzaldehyde through two different approaches involving Wittig olefination, hydrolytic kinetic resolution of a racemic epoxide, and olefin cross‐metathesis reaction as the key steps.

Metal free montmorillonite KSF clay catalyzed practical synthesis of benzoxazoles and benzothiazoles under aerobic conditions

Synthetic Communications (2019)

Vijaya Babu Kummari Chiranjeevi Kalavakuntla Alleni Suman Kumar Rathod Aravind Kumar J. S. Yadav

An efficient method for the synthesis of benzoxazoles and benzothiazoles via montmorillonite KSF clay catalyzed condensation reaction between 2-aminophenols or 2-aminothiophenols and β-diketones is reported. The efficiency of the reaction reflects from the wide substrate scope with electronic differentiation on aryls. The reaction is metal free and proceeds without the exclusion of air or moisture, and further the catalyst can be recycled up to 3–5 catalytic cycles.
