Cycloaddition reactions of 2-(indol-2-yl)acrylates and N-alkoxycarbonyl-1,2-dihydropyridine; new synthesis of desethylcatharanthine
Abstract
A new synthesis of desethylcatharanthine (7b) by utilising a cycloaddition reaction between the 2-(indol-2-yl)acrylate (10) and the N-alkoxycarbonyl-1,2-di-hydropyridine (4b) is described.
