The enantiocontrolled total synthesis of natural (–)-goniomitine
Abstract
The first enantiocontrolled total synthesis of (–)-goniomitine, a new structural type of indole alkaloid of the Aspidosperma family isolated from the root bark of Gonioma malagasy, has been completed starting from a chiral cyclopentadienone synthon and establishes the absolute stereochemistry as 20R, 21S.
