The crystal structure of the C12 rotaxane has been determined... An in-Triphenylaminophane [作者：SATHYAMOORTHI SHYAM; MAGUE JOEL T; PASCAL ROBERT A JR,期刊：Organic Letters, 页码：3427-3429 , 文章类型： Article，,卷期：2012年14-13] The synthesis and characterization of the triphenylamine-capped cyclophane 3 are described. It proved to be a conformationally rigid molecular propeller, with an inwardly pyramidalized, unreactive amine. A Silver(I)-Catalyzed Tandem Reaction of 2-Alkynylbenzaidoxime with Alkylidenecyclopropane [作者：XIAO QIAN; YE SHENGQING; WU JIE,期刊：Organic Letters, 页码：3430-3433 , 文章类型： Article，,卷期：2012年14-13] A silver(I)-catalyzed tandem reaction of 2-alkynylbenzaldoxime with alkylidenecyclopropane gives rise to benzo-7-azabicyclo[4.2.2]dec-7-en-4-ones in moderate to good yields. The complexity and diversity could be easily i... Kinetically Controlled One-Pot Formation of DEFGH-Rings of Type B Physalins through Domino-Type Transformations [作者：MORITA MASAKI; HIRAI GO; OHKUBO MEGUMI; KOSHINO HIROYUKI; HASHIZUME DAISUKE; MARUOKA KEIJI; SODEOKEA MIKIKO,期刊：Organic Letters, 页码：3434-3437 , 文章类型： Article，,卷期：2012年14-13] The characteristic DEFGH-ring system of type B physalins has been synthesized by means of a one-pot procedure incorporating domino-type ring transformations. Unexpectedly, we found that introduction of an alpha-hydroxyes...
