Sanjoinine-G1 (1), a 14-membered cyclopeptide, was synthesized with stereoselective reactions. Started from D-serine, a cyclic precursor for various frangulanine type 14-membered cyclopeptide alkaloids was synthesized and the side chain acylation product was identical with the natural sanjoinine-G1 (17 steps, overall yield 1.36%).
