Ss. Jew et al., ENANTIOSELECTIVE SYNTHESIS OF 20(S)-CAMPTOTHECIN USING SHARPLESS CATALYTIC ASYMMETRIC DIHYDROXYLATION, Tetrahedron : asymmetry, 6(6), 1995, pp. 1245-1248
The homochiral key intermediate 2 of 20(S)-camptothecin was prepared e
nantioselectively by using catalytic asymmetric dihydroxylation as the
key reaction.
