Abstract:

The Claisen rearrangement of benzylic substrates (benzyl vinyl ethers) has received considerably less attention than its well-known aliphatic and normal aromatic variants. Here, we review the rearrangement of both benzylic and heterobenzylic substrates, with examples of the reaction’s use in the synthesis of natural products and drug-like molecules.1 Introduction2 Early Attempts at the Benzyl-Claisen Rearrangement3 Successful Benzylic Examples4 Heterobenzylic Examples5 Conclusion

Abstract:

A range of chiral hydrogen-bond-donating organocatalysts was tested in the Ireland–Claisen rearrangement of silyl ketene acetals. None of these organocatalysts was able to impart any enantioselectivity on the rearrangements. Furthermore, these organocatalysts slowed down the Ireland–Claisen rearrangement in comparison to an uncatalyzed reaction. The catalyst-free reaction proceeded well in green solvents or without any solvent. DFT calculations showed that the activation barriers are higher for reactions involving hydrogen-donating organocatalysts and kinetic experiments suggest that the catal

Abstract:

Abstract7-Allylindolines are valuable synthons for designing biologically active molecular libraries. Lewis acid catalyzed amino-Claisen rearrangement provides a one pot synthetic entry to these heteroarenes. In this context, Zinc chloride (ZnCl2)–N,N-dimethylformamide system efficiently catalyzed amino-Claisen rearrangements of 1-N-allylindolines to 7-allylindolines. The rearrangement is influenced by stereoelectronic effects of substituents present in 1-N-allylindolines. The substrates containing electron donating functionalities underwent rearrangement at lower temperature than substrates w

Abstract:

An efficient and rapid method is described for the reductive Claisen rearrangement of different propargyloxyanthraquinones to anthra[1,2-b]furan-6,11-diones for first time using iron powder in a mixture of two ionic liquids, namely 1-methylimidazolium tetrafluoroborate [Hmim]BF4 and 1-benzyl-3-methylimidazolium chloride [Bzmim]Cl. The present method is able to execute single or double Claisen rearrangements of 1,4- or 1,5-bispropargyloxyanthraquinones selectively, so that the desired anthra(mono)furandiones or anthra(bis)furandiones are produced, respectively, as the major product.

Abstract:

The dissertation describes Pd0-catalyzed formal 1,3-diaza-Claisen rearrangement and the design and development of cationic 1,3-diaza-Claisen rearrangement. Our previous work has shown that isocyanates react with azanorbornenes and azabicyclo[2.2.2]octenes under thermal conditions to afford zwitterionic intermediates that undergo a thermal 1,3-diaza-Claisen rearrangement to give both ureas and isoureas. However, some azanorbornenes and azabicyclooctenes failed to rearrange or proceeded in low yields. To address these challenging substrates for the thermal 1,3-diaza-Claisen rearrangement, we hav

Abstract:

This thesis examines the issues of acyclic stereocontrol in the Claisen rearrangement, with particular emphasis on the effects of exopericyclic stereocentres – i.e. those adjacent to the array of atoms directly involved in the sigmatropic process. It is divided into three main parts: The first section provides a review of the field of acyclic stereocontrol. The models used to explain the development of relationships between stereocenters in systems lacking well-defined conformational constraints are discussed. This is an established field and particular emphasis is given to recent developments

Abstract:

Synthetic approaches towards linear fused carbon rings have been developed over the last decades due to their high interest as compounds with potential antibiotic activity and as organic electronics. The application of a novel iterative route towards linear fused carbon ring systems could provide a versatile new mode of access to complex substituted ring systems. Studies have previously demonstrated the use of an allylation-double Claisen-RCM sequence to build fused carbon rings (C). In this thesis we described our work to expand the use of this methodology by developing milder reaction condit

Abstract:

Microwave (MW) heating benefits organic synthesis by affording higher product yields in shorter time periods than conventional heating, yet it suffers from poor scalability and is limited to polar solvents in typical batch mode reactors. Herein, we report a microwave flow reactor using a solid-state semiconductor MW generator. The tunable, single-mode MW heating allows high efficiency, scalable organic synthesis, rapid reaction optimization and is applicable to non-polar solvents (o-Xylene and CPME can be rapidly heated to ca. 260 oC). Auto-frequency tuning compensates for changes in the micro
