Abstract
Herein, we report the synthesis of aryl derivatives of ketamine and of ketamine's major metabolites hydroxynorketamine (HNK), norketamine (NK), and dehydronorketamine (DHNK) via a microwave-assisted Diels-Alder reaction to form the substituted cyclohexane core structure. Starting with aryl acrylic esters as dienophiles and siloxybutadienes as diene counterparts, a wide range of substituted arylcyclohexylamines was obtained after several modification steps of the initial Diels-Alder products [El Sheikh, S.; Weber, H.; Kortenbrede, L.; Drouvé, N. A broadly applicable Diels-Alder based Synthesis of Ketamine related Arylcyclohexylamines. ChemRxiv 2022, 10.26434/chemrxiv- 2022-xf1l9].
