Lincomycin analogues. I. Chain-extensions of [1,2:3,4]-di-O-isopropylidene-α-D-galacto-hexodialdo-1,5-pyranoseThe title aldehydosugar 1 treated with Wittig reagents led in good to excellent yields to the unsaturated sugar derivatives 3-7 and 10-15, 8 having been prepared by condensation of 1 with malonic acid. The configuration (Z or E) of each compound obtained has been established by 1H-NMR. These chain-extensions constitute the first synthetic step towards the preparation of lincomycin analogues.
