N′-Benzylidene-N-homoallylacetohydrazides were designed and synthesized as novel
skeletons for the construction of functionalized tetrahydropyridazines. A series of aryl-and …

The tetrahydropyridazines motif widely presents in a plenty of natural products and
biologically active molecules. Easily prepared from the condensation of carbonyls with …

A facile and efficient approach for the synthesis of multisubstituted tetrahydropyridazines
starting from cyclopropyl ketones and hydrazines has been developed. The transformation is …

Here, we report the organocatalytic enantioselective synthesis of dihydrothiopyran
derivatives from trans racemic donor–acceptor cyclopropane carbaldehydes (DACCs) and 2 …

A Lewis-acid-promoted domino ring-opening cyclization of readily available donor–acceptor
cyclopropanes with a preinstalled electrophilic center, embedded in a donor group, to …

Here, we present a new approach for the activation of donor–acceptor cyclopropanes in ring-
opening reactions, which does not require the use of a Lewis or Brønsted acid as a catalyst …

Ytterbium triflate catalysed domino reaction of (3‐formyl‐4‐indolyl)‐derived donor‐acceptor
cyclopropane with primary amines provides a simple approach to an unprecedented …

Herein we report the discovery and development of the first example of a cationic [1, 5]‐aryl
migration reaction, through an unprecedented phenonium ions. This reaction does not …

A simple and efficient approach for the synthesis of privileged oxime esters by employing
donor-acceptor cyclopropane diesters (DACs) as one of the potential precursors is reported …

Here, we present a new approach for activation of donor-acceptor cyclopropane systems in
ring-opening reactions, which does not require the use of Lewis or Brønsted acid as a …
