The asymmetric syntheses of 6-deoxyerythronolide B (1) and oleandolide (2) have been achieved, each in 18 linear steps. These syntheses demonstrate the utility of chiral β-keto imide building block 3 as a versatile building block for the aldol-based assemblage of polypropionate-derived natural products.
Oleandomycin has been reconstructed by an introduction of the two sugar units onto the intact aglycone, oleandolide, which was first synthesized through the stereoselective oxidation of the 8-exo-methylene derivative.
