C. Cativiela et al., A SIMPLE SYNTHESIS OF (-)-(1S,2R)-ALLOCORONAMIC ACID IN ITS ENANTIOMERICALLY PURE FORM, Tetrahedron : asymmetry, 6(1), 1995, pp. 177-182
(-)-(1S,2R)-Allocoronamic acid was synthesized in its enantiomerically
pure form by starting from the chiral azlactone derived from 1,2-O-is
opropylidene-D-glyceraldehyde in an overall yield of 37%.
