Heterocycles are an extraordinarily important class of compounds, making up more than half
of all known organic compounds. Heterocycles are present in a wide variety of drugs, most …

For over a century, ketenes have intrigued organic chemists with their unusual physical
properties and unique spectrum of chemical reactivity; it is not an exaggeration to say that …

The carbonylation of carbenes through catalytic cycles is highly desirable due to the
importance of ketene-mediated reactions in organic synthesis. In this investigation, a highly …

The development of gold (I)‐catalyzed intermolecular carbo‐and hetero‐cycloadditions of
alkynes and allenes has been more challenging than their intramolecular counterparts. Here …

The chemistry of cyclic imines has been gaining importance in the last decade because of
their broad spectrum of applications and biological importance. This review focuses on the …

Visible light-induced cross-dehydrogenative coupling is a general and highly efficient
protocol for the synthesis of functionalized benzazepines/ones in a one-pot fashion, and is …

Selective structural modification of amino acids and peptides is a central strategy in organic
chemistry, chemical biology but also in pharmacology and material science. In this context …

Tetrahydroisoquinoline and its fused polyheterocycles are prevalent structural motifs found
in numerous natural products. In this study, we report a highly efficient and convergent …

A gold-catalyzed intermolecular reaction of propiolic acids with alkenes led to a [4+ 2]
annulation or enyne cross metathesis. The [4+ 2] annulation proceeds with net cis-addition …

An efficient strategy for the one-pot synthesis of polysubstituted pyridines via a cascade
reaction from aldehydes, phosphorus ylides, and propargyl azide is reported. The reaction …
