A STUDY ON THE AMINOMERCURATION-NUCLEOPHILIC DEMERCURATION OF CIS-CIS-1,5-CYCLOOCTADIENE - STEREOSELECTIVE SYNTHESIS OF 2,6-DISUBSTITUTED-9-AZA BICYCLO[3.3.1]NONANES
The aminomercuration of cis-cis-1,5-Cyclooctadiene with a series of mercury(II) salts followed by nucleophilic displacement of mercury by aromatic amines, water and nitrate ion has been studied. As a result, bicyclic triamines, aminoalcohols and nitrate esters have been obtained respectively in clean processes which occur under total stereoelectronic control by involvement of a tricyclic aziridium ion to afford a single stereoisomer in each case, The influence of the counter ion and the basicity of the amine on the tandem aminomercuration-demercuration is discussed.
