First systematic chiral syntheses of two pairs of enantiomers with 3, 5-dihydroxyheptenoic acid chain, associated with a potent synthetic statin NK-104
First systematic chiral syntheses of two pairs of enantiomers with 3, 5-dihydroxyheptenoic acid chain, associated with a potent synthetic statin NK-104 are reported. A pair of syn diol isomers (NK-104 and its enantiomer) was obtained efficiently by diastereomeric resolution. The synthesis of a pair of anti diol isomers (3-epimer and 5-epimer) was accomplished effectively by the asymmetric aldol reaction followed by anti stereoselective reduction as ...
