This review highlights key reactivities relying on C–C bond cleavages of cyclopropenes.
Metal-catalyzed and metal-free transformations are covered in reactions involving direct ring …

Heterocyclic rings are the fundamental building blocks of biological systems and have wide
applications in synthetic chemistry and medicinal science. The development of novel …

A new metal-free synthesis of pyrrole from allyl ketone and amine has been established. The
reaction proceeds via an thiolative activation of the C–C double bond with dimethyl …

This study describes an efficient approach to access oxime ethers via P (III)-mediated O–H
bond insertion reaction of oximes with α-keto esters. The strategy involves the protonation of …

A green and simple approach was developed for the regioselective synthesis of structurally
diverse chromenopyrrole frameworks from 3-formylchromones, active methylenes, and α …

We have developed a tandem method essential for synthesizing sulfone-containing organic
molecules, which has wide-ranging applications in agrochemicals, medicinal chemistry, and …

Generation of multi-substituted pyrroles is accomplished through an unexpected iron (II)-
promoted reaction of N-arylprop-2-yn-1-imines with water. This transformation proceeds …

Ene-cyclopropenes give functionalized indanes and tetralines in the presence of ruthenium
dimeric catalysts. This reaction involves the cyclopropene opening by the metal catalysts …

A one pot alkenylation followed by a stereoselective Alder-ene cycloisomerization of
cyclopropenes give (aza) spiro [2.4] heptanes and spiro [2.5] octanes in high yields. Total …

Copper is an abundant, low cost, and redox‐plural (0/I/II/III) transition element, and
frequently, its salts or complexes are used for efficient molecular transformations of natural …
