A Formal Synthesis of (+/-)-Cephalotaxine via Pauson-Khand Reaction [作者：XING PING; HUANG ZUOGANG; JIN YUN; JIANG BIAO,期刊：Synthesis, 页码：596-600 , 文章类型： Article，,卷期：2013年45-5] A concise route toward the formal synthesis of (+/-)-cephalotaxine has been developed. An intermolecular Pauson-Khand reaction was adopted to construct the cyclopentenone ring efficiently with high regioselectivity. Enantioselective Synthesis of Highly Substituted Chromans by a Zinc(II)-Catalyzed Tandem Friedel-Crafts Alkylation/Michael Addition Reaction [作者：LI CHAO; LIU FENGLEI; ZOU YOUQUAN; LU LIANGQIU; CHEN JIARONG; XIAO WENJING,期刊：Synthesis, 页码：601-608 , 文章类型： Article，,卷期：2013年45-5] An enantioselective tandem Friedel-Crafts alkylation/Michael addition reaction of 1-methylindoles with nitroolefin enoates catalyzed by a chiral tridentate bisoxazoline-Zn(II) complex has been described. This method prov... Iron(III)-Catalyzed Dehydration C(sp(2))-C(sp(2)) Coupling of Tertiary Propargyl Alcohols and alpha-Oxo Ketene Dithioacetals: A New Route to gem-Bis(alkylthio)-Substituted Vinylallenes [作者：LI QIAN; WANG YEMING; FANG ZHONGXUE; LIAO PEIQIU; BARRY BADRUDEEN; CHE GUANGBO; BI XIHE,期刊：Synthesis, 页码：609-614 , 文章类型： Article，,卷期：2013年45-5] A new and efficient synthetic approach to [gem-bis(alkylthio)vinyl]allenes has been developed involving iron(III)-catalyzed dehydration C(sp(2))-C(sp(2)) coupling of tertiary propargyl alcohols and alpha-oxo ketene dithi...
