The enantioselective synthesis of (−)-eusiderins A (1), B (2), G (25), L (23), M (5) and (+)-eusiderin C (20) and a range of analogues was undertaken using an efficient, divergent synthesis all from a single chiral aldehyde 15, which was derived from (S)-ethyl lactate 9. A comprehensive set of NMR data along with ECD spectra and optical rotation measurements of the synthesized natural products and
