《说吧,记忆》的“桔状结构”叙事

纳博科夫在自传小说《说吧,记忆》中运用了桔状结构的叙事手法,使得叙事具有空间化风格特征。《说吧,记忆》的桔状结构叙事手法与纳博科夫断裂的时间感受相关,他凭借空间化的叙事手段在写作中获得一种象征性的共时性时间体验,并使得作品具有众声喧哗的后现代美学风格。     

Catalytic Markovnikov and anti-Markovnikov functionalization of alkenes and alkynes: recent developments and trends

The regioselective functionalization of terminal alkenes and alkynes is of utmost importance for the synthesis of a wide variety of organic products. Based on the original observation by Vladimir Markovnikov-the pioneer of this field of research-in the 19th century, the possible regioisomeric products are classified as Markovnikov or anti-Markovnikov products. Contrary to traditional belief, it is nowadays possible to control the regiochemistry of various additions of nucleophiles to alkenes and alkynes by applying different transition-metal catalysts. Recent developments in this area of selective functionalization of alkenes and alkynes are reviewed.     

论《塞巴斯蒂安·奈特的真实生活》的后现代叙事艺术

《塞巴斯蒂安·奈奈特的真实生活》的主线是一场如真似幻的追寻。小说叙事者V自称是已逝作家塞巴斯蒂安同父异母的弟弟,他为了给哥哥写一部精准可靠的传记,费尽心思探访其剑桥同窗、工作助手以及曾经的女友。可惜,他得到的材料大多是经旁人转述的二手材料或者是经过商业加工的传记,甚至连叙事者V本身的身份也愈来愈模糊不清、令人怀疑。小说以＂真实＂为题,整部小说中却找不到＂真实＂的证据：这种游离的、无中心的、多重意义的文本恰恰是后现代主义的特点。     

VLADIMIR PRELOG

Vladimir Prelog, one of the truly influential organic chemists of the past century, died in Zurich after a short illness on 7 January 1998. For his contributions to stereochemistry, he shared the 1975 Nobel Prize in Chemistry with J.W. Cornforth. In his 1991 autobiographical sketch (53) 1 Prelog told what he wanted to tell about himself and his work. The present memoir borrows heavily on this, but we have also drawn on our own perceptions gathered over many years of companionship and communion.
