A newroute to the synthesis of the isocryptolepine alkaloid with antimalarial activity using a modified Pictet–Spengler reaction has been devised. The strategy was then used to generate libraries based on three structural variants of the alkaloid. Compounds based on these three variants in general were accessed in three steps through a modified Pictet–Spengler cyclization reaction as the key step
