Abstract: A cobalt‐catalyzed C−H carbonylation of benzoyl hydrazides has been developed by using 2‐(1‐methylhydrazinyl)pyridine as the bidentate directing group. This transformation is mild, efficient, operationally simple, and highly functional‐group‐tolerant. The protocol has generated a broad range of phthalimide derivatives in good to excellent yields. The ligand moiety can be readily removed through hydrogenolysis. [ABSTRACT FROM AUTHOR]

Abstract: A unified protocol for the construction of 6H‐benzofuro[2,3‐b]indoles and 5,6‐dihydroindolo[2,3‐b]indoles via UV light‐mediated diradical cyclization was developed and preliminary efforts were also made to functionalize at C10b position of 6H‐benzofuro[2,3‐b]indoles. This mild and facile strategy may have great potential in the syntheses of natural products and functional materials. [ABSTRACT FROM AUTHOR]

Described herein is the first asymmetric total synthesis of (+)-harringtonolide, a natural diterpenoid with an unusual tropone imbedded in a cagelike framework. The key transformations include an intramolecular Diels-Alder reaction and a rhodium-complex-catalyzed intramolecular [3+2] cycloaddition to install the tetracyclic core as well as a highly efficient tropone formation.

A new decarboxylative Csp3–Csp3 coupling approach for the benzylation of ketone enolates has been developed. A variety of raspberry ketone derivatives were conveniently synthesized in good to excellent yields under mild conditions. A crossover reaction shed light on the mechanism of this tandem reaction.

A novel one-step synthetic approach to tetrahydro[1,2]diazepinones via base-promoted rearrangement of α,β-epoxy-N-aziridinylimines, derived from α,β-epoxyketones and N-aminoaziridines, has been developed. [ABSTRACT FROM AUTHOR]

Abstract: The rearrangement of 6‐diazo‐2‐cyclohexenones is investigated and found to tolerate substrates bearing alkyl, alkenyl, and aryl substituents with a substituent in position 5 being essential for the formation of the desired products. [ABSTRACT FROM AUTHOR]
