Most of the efforts of organic chemists have been directed to the development of creative
strategies to build carbon–carbon and carbon–heteroatom bonds in a predictable and …

Methylene-and alkylidenecyclopropanes (MCPs and ACPs, 1, Figure 1) and-cyclobutanes
(MCBs and ACBs, 2, Figure 1) are highly strained molecules, but at the same time most of …

Heterocyclic compounds, which represent almost two-thirds of all the known organic
compounds, include some of the most significant for human beings. It is not surprising …

Since the first discovery of carbocupration of alkynes in the 1970s a tremendous amount of
research has been carried out in this field. The exceptionally high selectivities obtained …

When more complex system leads to simpler reactivity profile; the ring‐opening of strained
three‐membered rings such as methylene‐and alkylidenecyclopropanes generally lead to …

Vinylidenecyclopropanes (VDCPs) 1, which have a strained cyclopropyl group connected to
an allene moiety and yet are thermally stable and reactive substances in organic chemistry …

The importance of strained carbocycles such as three-membered rings has long been
recognised in organic chemistry. 1 Indeed, organic chemists have always been fascinated …

Since the methylenecyclopropane moiety is found in many biologically active natural
substances, the synthesis of methylene‐and alkylidenecyclopropanes remains a …

The copper‐catalyzed carbomagnesiation reaction of cyclopropenyl esters 1 leads to
various substituted cyclopropanes species 3 in good yields with very high …
