Lewis Acid Catalyzed Addition of Allylsilane to o-Quinonediimides: Formal Diels-Alder Reaction Versus Allylation

Vijay Nair, G; Dhanya, R; Vidya, N; Devipriya, S (Thieme, 2006)

Lewis acid promoted addition of allylsilane to o-quinonediimines afforded tetrahydroquinoxaline derivatives or allylated amides, depending on the nature of the substituent on the imine nitrogen.
Lewis Acid Promoted Regioselective Double Hydro(hetero)arylation of 6,6′-Dialkyl-Substituted Pentafulvenes: A Facile Approach to Bisindole Derivatives

Sasikumar, P; Prabha, B; Chand, S S; Aswathy, M; Madhukrishnan, M; Preethanuj, P; Suresh, E; Jaroschik, F; Radhakrishnan, K V (Wiley, 2017-08-17)

A Lewis acid catalyzed double hydro(hetero)arylation of alkyl-substituted pentafulvenes for the synthesis of bisindolesubstituted cyclopentenoids has been developed. The scope of the reaction was explored with a wide range ...
Lewis-Acid-Catalyzed Activation of Zerumbone towards Sesquiterpenoid Derivatives: Sustainable Utilization of Abundant Natural Resources for the Synthesis of Chemically Diverse Architectures

Dhanya, B P; Greeshma, G; Sasikumar, P; Neethu, S; Meenu, M T; Sharathna, P; Jubi, John; Sunil, Varughese; Sabu, M; Dan, M; Radhakrishnan, K V (Wiley, 2018-01-08)

A facile Lewis-acid-catalyzed method for the synthesis of structurally diverse sesquiterpenoid derivatives from readily available and abundant 11-membered natural product zerumbone has been developed. Starting from ...
Palladium/Lewis Acid Catalyzed Desymmetrization of Fulvene-Derived Bicyclic Hydrazines: A Facile Synthesis of Substituted Alkylidene Cyclopentenes

Anas, S; Sajisha, V S; Smitha, M; Radhakrishnan, K V (Thieme, 2006)

Desymmetrization of fulvene-derived bicyclic hydrazines by a palladium/Lewis acid catalyzed reaction with allyl and vinyl stannanes leading to the efficient synthesis of synthetically important alkylidene cyclopentenes is ...
Sequential Tandem Transformations of Functionalized Diazanorbornenes: Facile Strategy towards Pentacyclic Frameworks with Multiple Stereocenters

Preethanuj, P; Jijitha, V; Ajesh, V; Jubi John; Radhakrishnan, K V (Thieme, 2017-04)

The design, synthesis, and comprehensive utilization of diazanorbornene systems incorporating a flexible hydroxy group are described. The Lewis acid catalyzed intramolecular rearrangement of these strained alkenes gave ...
