This is probably the single most important reaction of carboxylic acid derivatives. The overall transformation is defined by the following equation, and may be classified either as nucleophilic substitution at an acyl group or as acylation of a nucleophile. For certain nucleophilic reagents the reaction may assume other names as well. If Nuc-H is water the reaction is often called hydrolysis, i...
A stereoselective synthesis of the monodeuterated methyleneaziridine shown allowed stereochemical course formal SNV-mode ring-opening with copper-based organometallics to be assigned.
The N-arylindole subunit is an important species in many biologically active and pharmaceutically important compounds, which display antiestrogen [1], analgesic [2], antiallergy [3], antimicrobial [4], and neuroleptic activity [5]. Although the traditional coppercatalyzed coupling of an aryl halide with a heteroatombased nucleophile, the Ullmann-type coupling reaction, has remained a standard m...
