  Preparation of the C1∼C10 fragment of carbonolide B. A relay approach to carbomycin B

  摘要：

  Reaction of methyl 2,3-anhydro-5,6-O-cyclohexylidene-beta-D-allofuranoside with 2-methyl-2-propenylmagnesium chloride selectively gave methyl 5,6-O-cyclohexylidene-3-deoxy-3-C-(2-methyl- 2-propenyl)-beta-D-glucofuranoside, which was convened into the C1 similar to C10 fragment of carbonolide B by a sequence of reactions involving hydroboration of the prochiral double bond, oxidative cleavage between C5-C6, and subsequent stereoselective three-carbon elongation at the C5 position.
