Recent synthetic developments in a powerful imino Diels–Alder reaction (Povarov reaction): application to the synthesis of N-polyheterocycles and related alkaloids
TL;DR: In this paper, a review is devoted to the development in Povarov reaction and focuses on new efficient approaches based on this reaction to construct simple substituted (tetrahydro)quinolines and diverse N -polyheterocycles, including some alkaloids, which contain pyrroloquinoline or cyclopentaquinoline ring systems.

αβ-UNSATURATED ETHERS AND THEIR ANALOGUES IN REACTIONS OF DIENE SYNTHESIS
TL;DR: In this paper, the αβ-unsaturated ethers and their analogues were studied and the mechanism of diene condensations was described. But the results were limited to αβunsaturated ensembles.
