Two Enantioselective Syntheses of the Diol Precursor of the Biologically Most Active Isomer of an Insect Growth Regulator

Article abstract of DOI:10.1016/S0957-4166(00)82223-5

The diol precursor (R)-3 of the insect growth regulator 2 was synthesized enantioselectively by two different routes: a) via enantioselective hydrogenation of the α-hydroxy-ketone 4, catalyzed by Ru-BINAP-catalyst and b) via resolution of the enantiomers of glycerol using (-)-camphor-10-sulfonamide 7 as chiral auxiliary.
