A convergent approach to cyclopeptide alkaloids: Total synthesis of sanjoinine G1

A general strategy for the synthesis of cyclopeptide alkaloids containing an endocyclic aryl-alkyl ether bond has been developed featuring a key intramolecular SNAr reaction. The importance of the N-terminal protective group in the realization

An asymmetric total synthesis of sanjoinine G1

A convergent total synthesis of sanjoinine G1, a 14-membered cyclopeptide alkaloid was described. Formation of aryl-alkyl ether bond with concomitant construction of macrocycle by way of an intramolecular SNAr reaction was the key step in this synthesis.
