Isocyanide (isonitrile) chemistry began in 1859 when Lieke obtained the first compound of
this type. 1 In 1958, isocyanides became generally available by dehydration of formamides …

Abstract The transition-metal-catalyzed [2+ 2+ 2] cycloaddition of alkynes is a useful and
atom-economical method for the synthesis of substituted benzenes. This comprehensive …

In the presence of a catalytic amount of Cp* RuCl (cod), 1, 6-diynes chemoselectively
reacted with monoalkynes at ambient temperature to afford the desired bicyclic benzene …

Abstract The [2+ 2+ 2] cycloaddition strategy is complementary to the well known Diels–
Alder reaction for the generation of polycyclic compounds. This [2+ 2+ 2] approach is atom …

The cyclotrimerization of acetylenic compounds is a useful method for the construction of
three new bonds in a one-step process. Although symmetry-allowed, there is a paucity of …

The building block approach was identified as a useful alternative to the commonly used
Bücherer− Berg method for the preparation of cyclic unusual α-amino acid derivatives. The …

A highly regioselective intermolecular cyclotrimerization of terminal alkynes has been
developed based on the use of the cationic rhodium (i)/DTBM‐Segphos complex. This …

Here we describe several useful strategies to a variety of unusual α-amino acid derivatives
and peptides based on “building block” approach. These building blocks are suitable for …

Cationic rhodium (I)/modified BINAP complexes are effective catalysts for highly
regioselective intermolecular cyclotrimerization of terminal alkynes and highly chemo-and …

We have developed a cationic rhodium (I)/modified-BINAP complex-catalyzed
chemoselective [2+ 2+ 2] cycloaddition of alkynes with isocyanates leading to a wide range …
