Takai, Kazuhiko Toshikawa, Shota Inoue, Atsushi Kokumai, Ryo Stereoselective Iodocyclopropanation of Terminal Alkenes with Iodoform, Chromium(II) Chloride, and <i>N</i>,<i>N</i>,<i>N</i>‘,<i>N</i>‘-Tetraethylethylenediamine Chemoselectivity of a reagent for (<i>E</i>)-olefination of aldehydes derived by reduction of iodoform with chromium(II) chloride in THF changes markedly by addition of TEEDA (<i>N</i>,<i>N</i>,<i>N</i>‘,<i>N</i>‘-tetraethylethylenediamine), and <i>trans</i>-iodocyclopropanes are produced stereoselectively from terminal alkenes by treatment with the base-added reagent system. The iodocyclopropanation occurs only at terminal double bonds, and di- and trisubstituted double bonds in the same molecules remained unchanged. Such functional groups as alcohol, ether, silyl ether, ester, tertiary amine, and amide groups are compatible with the reaction conditions. terminal alkenes;iodocyclopropanation;reaction conditions;stereoselectively;Terminal Alkenes;silyl ether;Chloride;olefination;chromium;Tetraethylethylenediamine;TEEDA;aldehyde;ester;Such;amide groups;chloride;iodoform;THF changes;molecule;tetraethylethylenediamine;reagent;Iodoform;trisubstituted;amine;tran;Chemoselectivity;Stereoselective Iodocyclopropanation;Chromium;iodocyclopropane;bond 2003-10-01
