Three new carbon–carbon bonds and up to five new stereocenters are created in the bicyclo
[2.2. 1] heptanones, such as 3, formed directly from a remarkable domino process involving …

We report the convergent synthesis of bicyclo [3.1. 0] hexanes possessing an all-carbon
quaternary center via a (3+ 2) annulation of cyclopropenes with cyclopropylanilines. Using …

Cyclopentenones serve as valuable synthetic building blocks and are themselves key
features in the structure of a number of prostaglandins [1] and other bioactive natural …

An efficient domino polycyclization combining different classes of pericyclic reactions leads
to complex spiroxindoles under mild conditions. This domino process represents a rare …

The atom-economical synthesis of carbocyclic eight-membered rings from double-and triple-
bond systems is a forte of organometallic catalysis. Nickel-catalyzed cyclotetramerizations 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 …

Stereoselective synthesis of a cyclopentane nucleus by convergent annulation constitutes a
significant challenge for synthetic chemists. Although a number of biologically relevant …

A diastereoselective two‐step strategy for the synthesis of densely functionalized 1‐
halocyclopentenes with several chiral centers has been developed. In the first step, a …
