Lithium Diisopropylamide‐Mediated Ring‐Opening of Tetrahydrofuran in the Synthesis of Polyhydroxylated Indolizidines

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step.
