The... Amines Bearing Tertiary Substituents by Tandem Enantioselective Carbolithiation-Rearrangement of Vinylureas [作者：TAIT MICHAEL; DONNARD MORGAN; MINASSI ALBERTO; LEFRANC JULIEN; BECHI BEATRICE; CARBONE GIORGIO; OBRIEN PETER; CLAYDEN JONATHAN,期刊：Organic Letters, 页码：34-37 , 文章类型： Article，,卷期：2013年15-1] In the presence of (-)-sparteine or a (+)-sparteine surrogate, organolithiums add to N-alkenyl-N'-arylureas to give benzylic organolithiums in an enantioselective manner. Under the influence of DMPU, these organolithiums... Cyclopropenone Catalyzed Substitution of Alcohols with Mesylate Ion [作者：NACSA ERIC D; LAMBERT TRISTAN H,期刊：Organic Letters, 页码：38-41 , 文章类型： Article，,卷期：2013年15-1] The cyclopropenone catalyzed nucleophilic substitution of alcohols by methanesulfonate ion with inversion of configuration is described. This work provides an alternative to the Mitsunobu reaction that avoids the use of ... A Highly Diastereo- and Enantioselective Hg(II)-Catalyzed Cyclopropanation of Diazooxindoles and Alkenes [作者：CAO ZHONGYAN; ZHOU FENG; YU YIHUA; ZHOU JIAN,期刊：Organic Letters, 页码：42-45 , 文章类型： Article，,卷期：2013年15-1] It is reported for the first time that Hg(II) can catalyze the cyclopropanation of diazo reagents and alkenes, which contributes to the unprecedented highly diastereo- and enantioselective synthesis of spirocyclopropylox... Asymmetric Chiral Ligand-Directed Alkene Dioxygenation [作者：NEUFELDT SHARON R; SANFORD MELANIE S,期刊：Organic Letters, 页码：46-49 , 文章类型： Article，,卷期：2013年15-1] A Pd-catalyzed asymmetric alkene 1,2-dioxygenation reaction is described. The diastereoselectivity of the reaction is controlled by tethering a chiral oxime ether directing group to the alkene substrate. The best selecti...
