Total Synthesis of the Cyclopeptide Alkaloid Sanjoinine G1 and Its C-11 Epimer. -An efficient new synthesis (18 steps, 6.6% overall yield) of sanjoinine G1 (VIII) is reported. The key steps in this synthesis are the formation of the alkyl-aryl ether linkage via an S N Ar reaction of amino alcohol (
Macrocylization via formation of aryl-alkyl ether bond was a key step in a model synthesis of 14-membered cyclopeptide alkaloids. A new chemoenzymadc synthesis of chiral 2amino-l-arylethanol was developed in the course of this study
