Pyrazolopyrimidine scaffolds are one of the most important heterocyclic compounds in drug discovery. This scaffold has various biological activities, among which anticancer is an important one.
Aziridines are highly strained three-membered heterocyclic molecules composed of one amine group and two carbon units. They are aza analogs of epoxides. Aziridines are a very important class of synthetic building blocks and intermediates in organic synthesis, which are widely used in organic synthesis, especially in the synthesis of nitrogen-containing natural products. Due to the high ring tension of aziridine, its reactivity is high. Under certain conditions, it can undergo cycloaddition reaction with various dipolar reagents to prepare some new nitrogen-containing heterocyclic compounds.

Tetrahydropyran is an organic compound consisting of a saturated six-membered ring containing five carbon atoms and one oxygen atom. Tetrahydropyrans are common structural motifs in natural products and synthetic therapeutic molecules. In nature, these six-membered oxygen heterocycles are usually assembled by intramolecular reactions, including oxygen Michael addition or ring opening of epoxy alcohols. In fact, polyether natural products have been particularly extensively studied for their fascinating structures and important biological properties; these are often formed through endoselective epoxy open cascades.
