Access to a new class of oxazaborinines using an efficient transition-metal-catalyzed rearrangement is demonstrated. The method overcomes the synthetic challenge of achieving an aza-Claisen rearrangement of vinylogous N-allylic amide substrates, giving rise to a variety of highly modifiable oxazaborinine products. An investigation of the unique reactivity of these boron-based heterocycles has unveiled their underexplored potential as valuable building blocks and intermediates for organic synthesis.

A novel and convenient method has been developed for the facile synthesis of functionalized succinimide derivatives via intramolecular Alder-ene reaction of 1,6-enynes. This reaction features mild and metal-free reaction conditions, which offers a green and efficient entry to synthetically important succinimide scaffolds. Preliminary mechanistic studies suggest that a diradical intermediate might be involved in this transformation.
Macrolactam Synthesis via Ring-Closing Alkene-Alkene Cross-Coupling Reactions

Reported herein is a practical method for macrolactam synthesis via a Rh(III)-catalyzed ring closing alkene-alkene cross-coupling reaction. The reaction proceeded via a Rh-catalyzed alkenyl sp2 C-H activation process, which allows access to macrocyclic molecules of different ring sizes. Macrolactams containing a conjugated diene framework could be easily prepared in high chemoselectivities and Z,E stereoselectivities.
