Electrosynthesis of alkaloids
Piperidine and isoquinoline derivatives form a large group of substance that are found in Nature and Pharmacenticals. Their biological properties prompted chemist to discover new synthetic tools aimed at the elaboration of new carbon to carbon bonds in the position  to the nitrogen atom. In this regard, the alkylation-decyanation sequence of new a-amino nitrile systems constitutes an efficient mean to achieve this goal and to control the absolute configuration of the newly created stereogenic center. In addition, the electrochemical synthesis of -amino nitriles has been little studied to date.
With this purpose in mind, new a-amino nitriles were elaborated through the anodic cyanation of conveniently substituted nitrogen containing derivatives such as N-aryl-piperidines, N-alkyl-isoquinolines and N-alkyl-quinolines. We were able to demonstrate that the introduction of the cyano substituent can be achieved in a regio- and stereoselective manner. In addition, the -proton can be removed efficiently with a strong base such as LDA to produce an -amino carbanion which can be condensed on a large variety of electrophiles. This strategy allowed the racemic syntheses of several major alkaloids such as coniine, solenopsin A, pumiliotoxin-C, alkaloid 241D, angustureine and galipinine (Figure 1).

Similarly, (+)-myrtine, (–)-crispine and (–)-xylopinine were synthesized in both enantiomeric forms utilizing (+) and (–)--phenylethylamine as a source of nitrogen and chirality (Figure 2).
