Application of Polyamines and Amino Acid Derivatives Based on 2-Azabicycloalkane Backbone in Enantioselective Aldol Reaction

2-Azabicyclo[3.2.1]octane scaffold: synthesis and applications

2-Azabicyclo[3.2.1]octanes are nitrogen containing heterocycles with significant potential in the field of drug discovery. This core has been applied as key synthetic intermediate in several total synthesis, while their unique structure can make them a challenging scaffold to acquire. This Minireview summarizes the synthetic approaches to access this bicyclic architecture and highlights its presence in the total synthesis of several target molecules.

Catalytic properties of 4,5-bridged proline methano- and ethanologues in the Hajos–Parrish intramolecular aldol reaction

The catalysis of the Hajos–Parrish reaction by cis- and trans-4,5-ethano-proline was explored experimentally and computationally with DFT (ωB97X-D and MN15) and DLPNO-CCSD(T).
