Common-Intermediate Strategy for Synthesis of Conduritols and Inositols via β-Hydroxy Cyclohexenylsilanes
摘要:
[GRAPHICS]Syntheses of conduritols B-D and F and (D)-(+)-chiro- and neo-inositols from cyclohexenyl si lane intermediates are described. The key cyclohexylsilane intermediates 5 and 14 were synthesized by stereoselective olefin dihydroxylation of the corresponding cyclohexenylsilanes. Selective Peterson elimination reactions and Fleming-Tamao oxidations of 5 and 14 then delivered the targeted cyclitol derivatives.
