ChemInform Abstract
The ester (V) and the lactone (X) are synthesized via the common intermediate (III) (space group P21/n; Z=4). Compound (V) is a precursor of (±)-emetine, protoemetinol and tubulosine; the lactone (X) contains the essential skeletal structure of the C, D and E rings of heteroyohimbine alkaloids such as ajmalicine.
