  名称：

  A stereochemical study on the intramolecular hydrosilylation of α,β-unsaturated esters

  摘要：

  The intramokcular hydrosilylation of several 3-methyl-4-siloxy-2-butenoates afforded cis disubstituted lactones after desilylation. The diastereoinduction was sensitive to the bulk of the allylic substituent, but not to the groups on silicon. The origin of asymmetric induction is believed to be the A1,2 strain from the beta-methyl group.

• Carotenoids and related polyenes. Part 4.1 Synthesis of carotenoid analogues containing a conjugated carbonyl group and their fluorescence properties

  日期：——

  Fluorescence properties of several synthetic carotenoid analogues have been investigated in order to assess the relationship between molecular structures and function as a photosynthetic antenna. The origin of fluorescence is determined by two factors; the length of the conjugated double bond system and the presence of a carbonyl group. For efficient energy transfer to chlorophyll a, eight conjugated double bonds and an associated carbonyl group are required, which ensures that fluorescence occurs from the S1 state.

  为了评估分子结构与作为光合天线的功能之间的关系，研究了几种合成类胡萝卜素类似物的荧光特性。荧光的起源由两个因素决定：共轭双键系统的长度和羰基的存在。为了有效地将能量转移到叶绿素a，要求具有八个共轭双键和一个相关的羰基，这确保了荧光从S1态发生。
