Acetylene systems present a new route to cyclic compounds as an
alternative to more traditional methods employed in classical
organic chemistry. The synthesis of cyclic structures based on
acetylene systems has important applications in the formation of
nanostructures, naturally occurring compounds and chemosensory
materials for the design of nonlinear optics, electronic and
photonic devices.

Alkynes in Cycloadditions presents a modern review of
regioselective synthesis of aromatic and non-aromatic carbocyclic
and heterocyclic ring systems based primarily on [2+2+2] and [4+2]
cycloadditions, and other reactions of acetylenic units including
enediynes and enyne-allenes.

Topics covered include:

* New strategies for the formation of aromatic and polynuclear
hydrocarbons based on (Z)-hex-3-en-1,5-diyne and
(Z)-hepta-1,2,4-triene-6-yne blocks.

* One-step synthesis of benzene derivatives, beta-substituted
naphthalenes and acenes by the cycloaromatization of enediynes and
enyne-allenes by Bergman, Myers-Saito and Shmittel.

* Mechanisms of cycloaromatization resulting in the formation of
fulvene and indene systems.

* Heterocyclization involving enyne-carbodiimides.

* New achievements in classical cycloaddition reactions such as
the Diels-Alder condensation with acetylenic dienophiles and [2+2]
cycloadditions with acetylene components

Alkynes in Cycloadditions presents a comprehensive
summary of the literature on methods for the synthesis of ring
systems from acetylenes for academic researchers working in the
fields of organic synthesis, physical organic chemistry,
organometallic chemistry, catalysis, materials science,
nanomaterials and biochemistry.
