A synthetic approach to terpendoles: decahydrobenzo[f]chromenes by an intermolecular Diels-Alder route

A Diels-Alder approach to (-)-ovalicin.

A fascinating aspect of the Diels–Alder reaction is its endo selectivity. This endo preference is much less pronounced in intermolecular cases compared with the intramolecular and transannular Diels–Alder (IMDA and TADA) reactions. Nevertheless, high endo selectivity is observed in the Diels– Alder additions of (E)-1-O-substituted dienes catalyzed by Lewis acids that lead to cis-1,6-disubstitut...

A direct route to 6,6'-disubstituted-2,2'-bipyridines by double Diels-Alder/retro Diels-Alder reaction of 5,5'-bi-1,2,4-triazines.

Inverse electron demand Diels-Alder reaction of functionalized 5,5'-bi-1,2,4- triazines with bicyclo[2.2.1]hepta-2,5-diene in boiling p-cymene leads to a range of 6,6'- disubstituted-2,2'-bipyridines in good yield.

Total synthesis of (+)-gelsemine via an organocatalytic Diels–Alder approach

The structurally complex alkaloid gelsemine was previously thought to have no significant biological activities, but a recent study has shown that it has potent and specific antinociception in chronic pain. While this molecule has attracted significant interests from the synthetic community, an efficient synthetic strategy is still the goal of many synthetic chemists. Here we report the asymmet...

The Diels-Alder Reaction: an Update

In this update on the Diels-Alder reaction we would like to present an overview on how this very important reaction has progressed in the last decade, since the last spate of monographs and reviews appeared in the literature, and which deal with the reaction in the overall sense. Initially we present the Diels-Alder reaction in a generalised form, much as discovered over seventy years ago, so t...
