supporting information, p. 6084 - 6096 (2015/05/27)
Plants of the species Gelsemium have found application in traditional Asian medicine for over a thousand years. Gelsemoxonine represents a novel constituent of this plant incorporating a highly functionalized azetidine at its core. We herein report a full
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

Complete regioselectivity is observed in palladium(0) catalyzed allylic substitution reactions of 1-vinylcyclopropyl 3 and cyclopropylldeneethyl esters 6 with a series of soft carbon nucleophiles to give γ-cyclopropylidene-1,3-dicarbonyl and 1-carbonyl-2-sulfonyl compounds. Highly functionalized mathylenecyclopropanes are thus obtained in good to excellent yields from easily accessible 1-vinylcyclopropyl tosylates 3d.
