Due to the synergistic “push–pull” effect of vicinal electron‐donating and electron‐
withdrawing groups, donor–acceptor (D‐A) cyclopropanes have been recognized as one of …

The effective use of ring strain has been applied to considerable advantage for the
construction of complex systems. The focus here is directed towards cyclopropanes as …

This review summarizes research directed towards the formation of carbocyclic adducts from
donor–acceptor cyclopropanes. The focus of the review is on annulation and cycloaddition …

Ring-opening transformations of donor–acceptor cyclopropanes (DAC) with carbon-
centered nucleophiles is a simple, straight-forward approach to 1, 3-bifunctional compounds …

A general, Brønsted acid catalyzed method for the room temperature, nucleophilic ring
opening of donor–acceptor cyclopropanes in fluorinated alcohol solvent, HFIP, is described …

Conspectus In asymmetric catalysis, the remote control of enantioselection is usually difficult
due to the long distance communication between the chiral center of the catalyst and the …

An efficient [4+ 3] cycloaddition reaction of D–A cyclopropanes with dienes has been
successfully developed. The reaction proceeds well with various dienolsilyl ethers in the …

Ringspannung gewinnbringend zu nutzen, ist seit jeher für den Aufbau komplexer Systeme
von großem Vorteil. Schnell richtet sich somit der Blick auf Cyclopropane als Bausteine für …

Lewis‐acid‐catalyzed reactions of 2‐substituted cyclopropane 1, 1‐dicarboxylates with
thioketones are described. Highly substituted tetrahydrothiophenes with two adjacent …

Abstract The MgBr2‐catalyzed formal [3+ 2] cycloaddition of donor–acceptor activated
cyclopropanes with nitrosoarenes offers a novel approach to various structurally diverse …
