Publication in Chemical Society Reviews (this post is for specialists only)

Recently, it has been published in Chemical Society Reviews a review I have been involved with my lab mates Lydia and Pernille.
For those who are familiar with organic chemistry, you will find the link to the original article below. Hope you enjoy reading it!

Find below the abstract:

Organocatalysis as a paint palette for asymmetric cycloaddition reactions.
Cycloaddition reactions are among the most important tools for the construction of cyclic compounds in organic synthesis, since these reactions are vital to access natural products and biologically active compounds. Organocatalysis plays an increasingly pivotal role in these reactions, often allowing several stereocenters to be selectively created and integrated in the target molecule. Among the large number of efficient types of organocatalysts available, the diarylprolinol silyl ethers have been established as one of the most frequently used in aminocatalysis allowing for novel activation modes and reaction concepts. In this review, we will focus on the different activation modes made available by the diarylprolinol silyl ether system with the aim of highlighting their applicability in asymmetric cycloadditions for the assembly of complex molecular architectures.

Synergistic Catalysis for the Asymmetric [3+2] Cycloaddition of Vinyl Aziridines with α,β-Unsaturated Aldehydes

Line Næsborg, Dr. Fernando Tur, Dr. Marta Meazza, Jakob Blom, Dr. Kim Søholm Halskov and Prof. Dr. Karl Anker Jørgensen

DOI: 10.1002/chem.201604995

Find below the abstract:

The first asymmetric [3+2] cycloaddition of vinyl aziridines with α,β-unsaturated aldehydes, based on synergistic catalysis, is disclosed. This methodology allows the formation of attractive pyrrolidine structures in good yields (up to 84 %), moderate diastereoselectivity, and high enantioselectivity values (up to >99 % ee). Additionally, a tricyclic pyrrolidine core structure found in biologically active molecules was synthesized in a one-pot fashion by using the presented reaction concept. Finally, a mechanistic proposal is outlined.
