Following a strong regain of interest over the past 20 years in the chemistry of allenes, this
“forgotten” family of unsaturated molecules is undergoing a renaissance. In this context, the …

After the long-held assumption of the unreactivity of gold, numerous reactions catalyzed by
this noble metal have been increasingly emerging in the literature over the past 2 decades …

Allenes have always fascinated chemists because of the intriguing features of the cumulated
diene function such as the higher reactivity compared to simple alkenes and the peculiar …

In the past four decades, allenes have progressively risen from an unenviable status of
being a structural curiosity to becoming one of the most powerful and versatile synthetic …

There is currently a rapidly growing interest in the homogeneous catalysis of organic
transformations by gold compounds. In a large number of specific studies, a wide variety of …

An organocatalyzed diastereo‐and enantioselective cascade aza‐Michael/Michael addition
of 2‐tosylaminoenones to unsaturated pyrazolones has been developed to afford novel …

A practical regioselective and diastereoselective synthesis of functionalized 1-benzo [b]
azepines by copper-catalyzed intramolecular cyclization has been developed. The reaction …

Aldehydes can be α-alkylated with allenamides by the combined action of an organocatalyst
and a gold complex. The reaction requires the simultaneous generation of an enamine and …

The heterogeneous gold-catalyzed cyclization of (o-alkynyl) phenoxy-or N-(o-alkynylphenyl)
tolylsulfonamidoacrylates with alcohols has been developed by using an MCM-41-anchored …

We report a simple protocol for the copper-catalyzed hydrothiolation of N-unsaturated
precursors, ie, allenamides, enamides, and ynamides, under mild conditions. This method …
