A new cyclopeptide alkaloid, sanjoinine-G1, has been isolated from the seeds of Zizyphus vulgaris var. spinosus. The structure and absolute configuration has been established by spectroscopic analysis and the circular dichroism exiton-coupling method, as N-[(S)(N',N')-dimethylphenylalanyll- cyclo[O-(2S,3S)-β-oxyleucyl-(S)-leucyl-(2-mino-(1R)-hydroxyethyl)-p-phenyl].
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.
