The ynamide functional group activates carbon–carbontriple bonds through an attached
nitrogen atom that bears an electron-withdrawing group. As a result, the alkyne has both …

Ketenimines are an important class of reactive species and useful synthetic intermediates.
During the last two decades several practical and versatile approaches to ketenimines have …

Using ynamides as readily available starting materials, a single step can generate highly
reactive ketenimines, which can then undergo a variety of transformations. The choice of the …

Gold carbene reactivity patterns were accessed by ynamide insertion into a C (sp3) H
bond. A substantial increase in molecular complexity occurred through the cascade …

We herein report the gold (III)-catalyzed selective annulation of anthranils with N-
allylynamides under mild conditions. By trap** the in situ-generated α-imino gold …

A detailed study of amidine synthesis from N-allyl-N-sulfonyl ynamides is described here.
Mechanistically, this is a fascinating reaction consisting of diverging pathways that could …

High-valent cobalt carbene Co (OR) 2 (═ CPh2)(OR= OC t Bu2Ph) undergoes reaction with
various isocyanides CNR′(CNR′= 2, 6-dimethylphenyl isocyanide, 4-methoxyphenyl …

A series of carbocyclization cascades of allyl ketenimines initiated through a thermal aza-
Claisen rearrangement of N-phosphoryl-N-allyl ynamides is described. Interceptions of the …

We describe here details of our investigations into Pd-catalyzed and thermal aza-Claisen–
carbocyclizations of N-allyl ynamides to prepare a variety of α, β-unsaturated …

The first synthesis of N-(acyloxy) ynamides was realized through the coupling of N-(acyloxy)
amides and hypervalent alkynyliodane under mild conditions. This reaction probably …
