reaction pathways of a wide variety of tethered alkenes can be accessed through changing the amide directing group. This provides an efficient route to a myriad of complex polycyclic products, many containing newly formed all‐carbonquaternary centers. Amidoarylations can diastereoselectively deliver products with up to three contiguous stereocenters.

Rhodium(II) acetate-catalysed reaction of ethyl 2-diazo-2-diethoxyphosphorylacetate 2 with carbamates, amides, ureas or anilines gives a range of N-substituted 2-amino-2-diethoxyphosphorylacetates 3–18 by N-H insertionreaction of the intermediate rhodium carbenoid.

hydroxamates derived from cyclobutenyl carboxylic acids were identified as viable substrates in intramolecular rhodium(III)-catalyzed heteroannulations, which led to diversely substituted cyclobuta[c]pyridones. Further functionalization of the resulting cyclobutapyridones enabled the synthesis of cyclobuta[c]pyridines and other nitrogen heterocycles after electrocyclic ring opening of the four-membered ring
The first total synthesis of racemic topsentin C, a secondary metabolite from Hexadella sp., based on this approach is reported. The initially proposed structure for topsentin C has been revised. An efficient syntheticapproach to access (indol-3-yl)ethane-1,2-diamines with a protecting group at the indole N atom from readily available 3-(2-nitrovinyl)indoles is reported. This approach includes solvent-free

one-pot, three-step synthesis demonstrated the utility of this protocol. Hybrid conjugates with an oseltamivir derivative further offered a powerful tool for the construction of a versatile spiroindole-containing library via click chemistry.
