A rather facile stereoselective totalsynthesis of (9S)-9-dihydroerythronolide A starting fromD-glucose was achieved via coupling of C1-C6 and C7-C15 segments and subsequent macrolactonization.
Chiral synthesis of polyketide-derived natural products. 27. Stereoselective synthesis of erythronolide A via an extremely efficient macrolactonization by the modified Yamaguchi method
