Rh2(OAc)4/CeCl3-catalyzed olefination of carbonylferrocenes with α-diazocarbonyl compounds: A convenient synthesis of alkenylferrocenes
Chen, Shufeng,Zhang, Lele,Du, Yan,Li, Baoguo
, p. 943 - 947 (2012)
A concise and efficient protocol for the synthesis of al-kenylferrocene derivatives based on the olefination of carbonylferrocenes with α-diazocarbonyl compounds using Rh2(OAc)4/CeCl 3 as efficient catalysts was developed. The present method was applicable to many kinds of substituted carbonylferrocenes and α-diazocarbonyl compounds providing good to excellent yields of desired products.

The Fujiwara-Moritani reaction has had a profound contribution in the emergence of contemporary C-H activation protocols. Despite the applicability of the traditional approach in different fields, the associated reactivity and regioselectivity issues had

The regio- and diastereoselective synthesis of oxazolidinonesviaa Pd-catalyzed vicinal C-N/C-Cl bond-forming reaction from internal alkenes of allylic carbamates is reported. The oxazolidinones are obtained in yields of 44 to 95% with high to excellent diastereoselectivities (from 6?:?1 to >20?:?1 dr) from readily available precursors. This process is scalable, and the products are suitable for the synthesis of useful amino alcohols. A detailed theoretical and experimental mechanistic study was carried out to describe that the reaction proceeds through ananti-aminopalladation of the alkene followed by an oxidative C-Pd(ii) cleavage with retention of the carbon stereochemistry to yield the major diastereomer. The role of Cu(ii) in a C-Cl bond-forming mechanism step has also been proposed.
Electrochemical Generation of a Nonstabilized Azomethine Ylide: Access to Substituted N-Heterocycles

Azomethine ylides are fascinating 1,3-dipoles for [3 + 2] cycloaddition reactions toward the construction ofN-heterocycles. Herein, an efficient and environmentally benign electrochemical approach for the generation of a nonstabilized azomethine ylide has been established under metal-free and external oxidant-free conditions. The resulting 1,3-dipole undergoes a [3 + 2] cycloaddition reaction with olefins. This electrosynthetic methodology indulges a straightforward and facile approach for the construction of substituted pyrrolidines.
