Stereocontrolled synthesis of erythronolides A and B in a (C5-C9) + (C3-C4) + (C1-C2) + (C11-C13) sequence from 1.6-anhydro-β-D-glycopyranose (levoglucosan). Part 1. Synthesis of C1-C10 and C11-C13 segments
An approach to the synthesis of aglycones of macrolide antibiotics erythromycine A and B is discussed and preparation of common C1-C10 and C1-C13 segments starting from levoglucosane is described.
