Olivo, Horacio F. Velázquez, Francisco Trevisan, Henrique C. Synthetic Studies on the <i>trans</i>-Chlorocyclopropane Dienyne Side Chain of Callipeltoside A Enantiomerically enriched <i>trans</i>-chlorocyclopropanemethanol was obtained by lipase kinetic resolution of dichlorocyclopropanemethanol <b>3</b>, followed by reduction. The sp<i>−</i>sp<sup>2</sup> bond of the <i>trans</i>-chlorocyclopropane dienyne side chain of callipeltoside A was constructed via a Stille coupling reaction of 1,1-dibromo-1-alkene <b>7</b> and a vinylstannane in a highly dipolar solvent capable of promoting HBr elimination to give internal alkynes. tran;chlorocyclopropane dienyne side chain;HBr elimination;dichlorocyclopropanemethanol 3;Chlorocyclopropane Dienyne Side Chain;sp;Synthetic Studies 2000-11-11
