Bicyclo under construction! The [RhCl (dppp) 2]‐catalyzed intramolecular [6+ 2]
cycloisomerization of alkyne–allenylcyclobutanes efficiently produced bicyclo [6.4. 0] …

Highly strained cyclopropane derivatives have served as useful and powerful C3 building
blocks [1] for the construction of various ring systems, and the metal-catalyzed cleavage of …

No templates needed: The title reaction makes it easy to construct the bicyclo [6.3. 0]
undecadienone framework in high yields (see scheme). A template effect is not required to …

Cyclopropane undergoes facile ring opening assisted by relief of the strain energy (27.5
kcalmolÀ1)[1] and is therefore a variable acyclic C3 building block [2] in various types of …

Developing efficient and general strategies to construct skeletally complex and diverse
polycyclic skeletons is important for both synthesis of natural products and chemical biology …

Build a bridge: The first catalytic intramolecular [3+ 2] cycloaddition of monodonor-
monoacceptor cyclopropanes (see scheme) provides a general and efficient strategy for …

A novel Lewis acid catalyzed formal intramolecular [3+ 3] cross-cycloaddition (IMCC) of
cyclopropane 1, 1-diesters has been successfully developed. This supplies an efficient and …

Previously reported was that cis‐ene‐vinylcyclopropanes (cis‐ene‐VCPs) underwent Rh‐
catalyzed [5+ 2] reaction to give 5, 7‐fused bicyclic products, where vinylcyclopropane …

In 1984, Rautenstrauch reported that the 3-acyloxy-1, 4-enyne 1 could undergo cyclization
to form cyclopentadiene 2 and cyclopentenone 3 in the presence of a palladium catalyst …

The intramolecular Diels–Alder (IMDA) reaction is a powerful strategy for the construction of
complex multicyclic skeletons.[1] The construction of the bridged multicyclic skeleton C, from …
