Da. Evans et al., GENERAL STRATEGIES TOWARD THE SYNTHESES OF MACROLIDE ANTIBIOTICS - THE TOTAL SYNTHESES OF 6-DEOXYERYTHRONOLIDE-B AND OLEANDOLIDE, Journal of the American Chemical Society, 120(24), 1998, pp. 5921-5942
The asymmetric syntheses of 6-deoxyerythronolide B (1) and oleandolide
(2) have been achieved, each in 18 linear steps. These syntheses demo
nstrate the utility of chiral beta-keto imide building block 3 as a ve
rsatile building block for the aldol-based assemblage of polypropionat
e-derived natural products.
