Molecules containing bridged bicyclic systems, such as the (7- hetero)bicyclo[2.2.1]heptane ring system, are interesting synthetic targets because these systems are present in many molecules with biologically relevant activity. Common precursors for these sytems are the (7-hetero)nobornadienes. This review covers the different approaches used in the last ten years for the synthesis of (7-hetero)norbornadienes through Diels- Alder (D-A) cycloaddition between cyclic dienes and alkynes. The review also shows the synthetic applications of these [2.2.1]bicyclic systems as intermediates in the preparation of other relevant molecules.

Functionalization of amines by using CO2 is of fundamental importance considering the abundance of amines and CO2. In this context, the catalytic formylation and methylation of amines represent convenient and successful protocols for selective CO2 utilization as a C1 building block. This study represents the first example of selective catalytic double N-formylation of aryl amines by using a dinuclear Mn complex in the presence of phenylsilane. This robust system also allows for selective formylation and methylation of amines under a range of conditions.

The methylation of amines using methanol is a promising route to synthesize N-methylamines, and the development of cheap and efficient catalytic system for this reaction is of great significance. Herein, we reported a cobalt (Co)-based catalytic system, which was in situ formed from commercially available Co precursor and a tetradentate phosphine ligand P(CH2CH2PPh2)3 combined with K3PO4. This catalystic system was very effective for the selective production of dimethylated products from aliphatic amines and monomethylated ones from aromatic amines.
