Organoborons have emerged as versatile building blocks in organic synthesis to achieve
molecular diversity and as carboxylic acid bioisosteres with broad applicability in drug …

Beginning as chemical curiosities with the pioneering work of Curtius, 1a Staudinger, 1b and
even earlier efforts, 1c carbenes have played an important role as transient intermediates …

Cyclopropanol and its derivatives are carbocyclic homologues of enols, and there is an
obvious similarity in chemical properties between these classes of compounds due to the …

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 …

We report a new method for the formal [3+ 2] reaction of aryl cyclopropyl ketones with olefins
to generate highly substituted cyclopentane ring systems. The key initiation step in this …

An unprecedented Rh (III)-catalyzed C–H activation/cycloaddition of benzamides and
methylenecyclopropanes for the selective synthesis of spiro dihydroisoquinolinones and …

The transition metal‐catalyzed formal [3+ 2] cycloaddition of methylenecyclopropanes with
unsaturated compounds X= Y, such as alkenes, aldehydes, and imines, gives five …

Although they are highly strained, methylenecyclopropanes (MCPs) are readily accessible
molecules that have served as useful building blocks in organic synthesis. MCPs can …

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 …
