Selective Cascade Reaction of Bisallenes via Palladium‐Catalyzed Aerobic Oxidative Carbocyclization–Borylation and Aldehyde Trapping

Angewandte Chemie International Edition (2017)

Veluru Ramesh Naidu Daniels Posevins Chandra M. R. Volla Jan‐E. Bäckvall

A cascade reaction, consisting of a palladium-catalyzed regioselective aerobic oxidative carbocyclization-borylation of bisallenes and a final aldehyde trapping, afforded triene alcohols with high diastereoselectivity. The cascade reaction occurs under mild reaction conditions and proceeds via an allylboron intermediate that is trapped by the aldehyde in a stereoselective manner.

Carbocations as Lewis Acid Catalysts: Reactivity and Scope

Advanced Synthesis & Catalysis (2014)

Juho Bah Veluru Ramesh Naidu Johannes Teske Johan Franzén

Abstract One class of potential Lewis acids that has received negligible attention as a catalyst is the carbocation. Here we show the potential of triarylmethylium ions as highly powerful Lewis acid catalysts for organic reactions. The Lewis acidity of the triarylmethylium ion can be easily tuned by variation of the electronic properties of the aromatic rings and the catalytic activity of the carbocation is shown to correlate directly to the level of stabilization of the empty p C ‐orbital at the cationic carbon. The versatility of triarylmethylium ions as efficient Lewis acid catalysts for organic reactions is demonstrated in Diels–Alder, aza‐Diels–Alder, conjugate addition, halogenation, epoxide rearrangement and intramolecular hetro‐ene reactions. magnified image

Synthesis of Cross-Conjugated Polyenes via Palladium-Catalyzed Oxidative C–C Bond Forming Cascade Reactions of Allenes

The Journal of Organic Chemistry (2020)

Veluru Ramesh Naidu Jan‐E. Bäckvall

An efficient palladium-catalyzed oxidative C–C bond forming cascade reaction of allenes involving a coupling between an enallene and an allenyne followed by a carbocyclization of the generated Pd-intermediate was developed. This cascade reaction afforded functionalized cross-conjugated polyenes. The enallene is initially activated by palladium and reacts with the allenyne to give the cross-conjugated polyenes.

Direct Organocatalytic Oxo‐Metathesis, a trans‐Selective Carbocation‐Catalyzed Olefination of Aldehydes

European Journal of Organic Chemistry (2015)

Veluru Ramesh Naidu Juho Bah Johan Franzén

Abstract A direct organocatalytic carbonyl/olefin oxo‐metathesis has been developed. The reaction is catalyzed by trityl tetrafluoroborate (TrBF 4 ) and utilizes unactivated alkenes for the olefination of aromatic aldehydes to give trans β‐alkylstyrenes in yields of 44–85 % with only acetone as the byproduct. The pronounced Lewis acidity of the carbocation results in unusual reactivity that is proposed to catalyze a stepwise [2+2] cycloaddition to give an oxetane intermediate. Fragmentation of the latter in a formal retro [2+2] reaction gives the oxo‐metathesis product.
