Iron-Catalyzed Cross-Coupling of 1-Alkynylcyclopropyl Tosylates and Related Substrates
1-Alkynylcyclopropyl tosylates react with alkylmagnesium halides in the presence of catalytic ferric acetylacetonate [Fe(acac)3] under net propargylic substitution; allene formation, which is the prevalent reactivity mode of propargylic substra
Versatile Synthesis of Enantiomerically Pure 2-Alkoxy-1-ethynylcyclopropanes and Their Application in the Synthesis of Enantiomerically Pure Bicyclo-oct-1-en-3-ones
A variety of chiral, nonracemic 2-alkoxy-1-alkynylcylopropanes 7 were synthesized in good to very good yields from enantiomerically pure glycidol derivatives (glycidol tosylate, epichlorohydrin) by boron trifluoride promoted addition of lithium trimethyls
