TOTAL SYNTHESIS OF SCELETIUM (AIZOACEAE) ALKALOIDS. THE CINNAMONITRILE ROUTE. THE TOTAL SYNTHESIS OF RACEMIC O-METHYL JOUBERTIAMINE AND MESEMBRINE
Sanchez, Ignacio H.,Tallabs, F. Ramon
, p. 891 - 894 (1981)
A new method of synthesis of Sceletium (Aizoaceae) alkaloids based on the introduction of a "formyl anion" equivalent at the β-position of a cinnamonitrile, followed by Robinson annulation and final modification of the resulting cyanomethyl side is described.The method has been succesfully applied to the total synthesis of racemic O-methyljoubertiamine (1) and mesembrine (2).
