Selenium, originally described as a toxin, turns out to be a crucial trace element for life that
appears as selenocysteine and its dimer, selenocystine. From the point of view of drug …

Ynamides are among the most powerful building blocks in organic synthesis and have
become invaluable starting materials for the construction of multifunctional compounds and …

Ynamides are special alkynes bearing an electron-withdrawing group on the nitrogen atom,
and they have been extensively studied over the past decade. However, the addition of …

A novel, one-step N-dehydrogenation of amides to enamides is reported. This reaction
employs the unlikely combination of LiHMDS and triflic anhydride, which serves as both the …

Ynamides are electron‐rich heteroatom‐substituted alkynes with C− C triple bond directly
tethered to the amide group. Over the past decades, ynamides have proven to be versatile …

Chiral propargyl amides are particularly useful structural units in organic synthesis. The
enantioselective synthesis of propargyl amide is highly desirable. Conventional approach …

A Pd‐catalyzed three‐component syn‐1, 2‐arylmethylation of internal alkynes
(ynamides/yne‐acetates/alkynes) is described. The readily available and bench stable …

We report here our results on the application of ynamides as substrates in the reactions with
diorganyl dichalcogenides and iron (III) chloride to give selectively three different types of …

This paper reports that tertiary α-azidyl phenyl ketones can be transformed into enamides by
treatment with FeBr2 at elevated temperature in DMF. The reaction proceeds via 1, 2 …

The highly enantioselective addition of terminal ynamides to a variety of isatins, catalyzed by
a bisoxazolidine copper complex under mild, base‐free reaction conditions, is described …
