First enantiocontrolled synthesis of sceletium alkaloid A-4: determination of the absolute configuration
Abstract
Sceletium A-4, a pyridine alkaloid isolated from the Sceletium species, has been synthesized for the first time in an enantiocontrolled manner along with (–)-mesembrine, an alkaloid isolated from the same plant, starting from a chiral cyclohexadienone synthon to determine the absolute configuration.
