T. Sunazuka et al., ASYMMETRIC-SYNTHESIS OF THE ANTICOCCIDIAL ANTIBIOTIC DIOLMYCIN-A1 - DETERMINATION OF ABSOLUTE STEREOCHEMISTRY, Tetrahedron letters, 34(42), 1993, pp. 6659-6660
An asymmetric total synthesis of diolmycin A1 (1), a recently discover
ed anticoccidial antibiotic, has been achieved in six steps from 2-(4-
hydroxyphenyl)ethanol. The natural product comprises an unusual ca. 4:
1 mixture of enantiomers; the synthesis defined the (11R,12S) absolute
configuration of the predominant (-) antipode.
