In 1992, Jack Baldwin, Robert Adlington, David Bebbington, and Andrew Russell accomplished the first asymmetric total synthesis of the individual diastereoisomers of hypoglycin A, using the Sharpless epoxidation to permit an asymmetric methylene cyclopropane synthesis. 1H NMR and circular dichroism studies identifies the major diastereoisomer of natural hypogycin A as (2S, 4R) and the minor diastereoisomer as (2S, 4S).
