Asymmetric Synthesis of Highly Functionalized 8-Oxabicyclo[3.2.1]octene Derivatives
TL;DR: In this paper, the authors considered the mechanism of the [3 + 4] annulation to be a tandem cyclopropanation/Cope rearrangement, which is consistent with the excellent regio- and stereocontrol that is observed in these annulations.

Asymmetric Synthesis of 2,3-Dihydrofurans by Reaction of Rhodium-Stabilized Vinylcarbenoids with Vinyl Ethers.
Huw M. L. Davies,Gulzar Ahmed,Rebecca L. Calvo,Melvyn Rowen Churchill,David George Churchill +4 more
TL;DR: Rhodium(II) octanoate catalyzed decomposition of 2-diazo-3-siloxybutenoates, containing (R)-pantolactone as a chiral auxiliary, in the presence of vinyl ethers results in the diastereoselective synthesis of cyclopropanes with high asymmetric induction.

Type II intramolecular annulations between vinylcarbenoids and furans
TL;DR: Rhodium(II) octanoate catalyzed intramolecular reactions between vinyldiazomethanes and furans result in the formation of polycyclic systems by a tandem cyclopropanation/Cope rearrangement as mentioned in this paper.

Divergent Pathways in the Intramolecular Reactions between Rhodium-Stabilized Vinylcarbenoids and Pyrroles: Construction of Fused Tropanes and 7-Azabicyclo[4.2.0]octadienes
TL;DR: The rhodium(II)-catalyzed intramolecular reaction between vinyldiazomethanes and pyrroles leads to a novel synthesis of fused tropanes.
