Although alkynes are one of the smallest functional groups, they are among the most
versatile building blocks for organic chemistry, with applications ranging from biochemistry …

Hypervalent iodine reagents are in high current demand due to their exceptional reactivity in
oxidative transformations, as well as in diverse umpolung functionalization reactions. Cyclic …

Here we present a modular, chemo‐, regio‐, and stereoselective synthesis of fully‐
substituted and configuration‐defined alkyl vinyl ethers (AVEs) using simple chemical …

For the first time, the monoalkoxycarbonylation of easily available 1, 3‐diynes to give
synthetically useful conjugated enynes has been realized. Key to success was the design …

A photochemical hydroalkynylation is reported employing a metallaphotoredox approach
using cobalt catalysis and an organic dye, 4CzIPN. The protocol enables catalysis without …

We report a gem‐specific homo‐and cross‐dimerization of terminal alkynes catalyzed by a
well‐defined iron (II) complex containing Cp* and picolyl N‐heterocyclic carbene (NHC) …

An anti-carbonickelative cyclization via reversible alkenylnickel E/Z isomerization of 2-azido
phenyl propargyl alcohols with aryl boronic acids is achieved using Ni (acac) 2 as the …

A general method for isoxazoles from readily available ynones using trimethylsilyl azide as
an amino surrogate, likely via an unprecedented hydroazidation of the alkyne and …

In recent years, gold catalysis involving Au (I)/Au (III) redox cycle has gained significant
attention. This account summarizes our contributions to the development of Au (I)/Au (III) …

[4+ 2] oxidative Diels–Alder reaction of readily available alkynols with maleimide is achieved
for the rapid access of pthalimide-fused multicyclic compounds. The reaction is proposed to …
