摘要:两种带有恶二唑基团作为侧链的新型高分子量官能化聚乙炔,聚(2-(4-癸氧基苯基)-5-(4-乙炔基苯基)-1,3,4-恶二唑)(P1)和聚(2-(4-通过多步反应路线设计并合成了丁氧基苯基)-5-(4-乙炔基苯基)-1,3,4-恶二唑)(P2).通过 Ftir,NMR,Uv,Tga,Gpc,光学限制 (Ol) 和非线性光学 (Nlo) 分析对结构和性能进行了表征和评估.将恶二唑引入聚乙炔中显着赋予聚乙炔更高的热稳定性和光限幅性能.柔性末端烷氧基链长度明显影响所得聚乙炔的溶解度,立构规整性和光学性质.聚乙炔主链中的顺式烯属结构含量随着端烷氧基长度的增加而增加.顺烯结构含量较高的功能聚乙炔表现出较高的热稳定性,较好的光限幅性能和较大的三阶非线性光学性能.研究了所得聚合物的光限幅机制,其主要源于分子较大的激发态吸收截面,导致反向饱和吸收.

标 题:Synthesis of rocaglamide natural products via photochemical generation of oxidopyrylium species
发明人：JONES II GUILFORD; GERARD BAUDOUIN; PORCO JR JOHN A
权利人:UNIV BOSTON
摘要:The present invention provides new strategies for the synthesis of compounds of the rocaglamide family and related natural products. In particular, the new biomimetic synthetic approach involves photochemical generation of an oxidopyrylium species from a 3-hydroxychromone derivative followed by 1,3-dipolar cycloaddition of the oxidopyrylium species to a dipolarophile. This approach can be used for the formation of adducts containing an aglain core structure. Methods for the conversion of aglain core structures to aglain, rocaglamide and forbaglin ring systems are also provided. The present invention also relates to the use of rocaglamide/aglain/forbaglin derivatives for the manufacture of medicaments for use in the treatment of cancer or cancerous conditions, disorders associated with cellular hyperproliferation, or NF-κB-dependent conditions.

标题 :Convergent synthesis of multiporphyrin light-harvesting rods
发明人：LINDSEY JONATHAN S; LOEWE ROBERT S
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.

标题:Use of functionalized onium salts as a soluble support for organic synthesis
发明人：VAULTIER MICHEL; GMOUH SAID; HASSINE FATIMA
权利人:CENTRE NAT RECH SCIENT; UNIV RENNES
摘要:The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula A₁⁺, X₁^-, wherein A₁⁺ represents a cation and X₁^- represents an anion.

标 题:Intermediates for steroid total synthesis process utilizing asymmetric induction
发明人：COHEN NOAL; SAUCY GABRIEL
权利人:HOFFMANN LA ROCHE
摘要:A multi-step, stereospecific total synthesis of steroids is disclosed. The starting materials for this process are the relatively inexpensive and readily available m-alkoxy acetophenones. The process is suitable for the preparation of racemic or optically active, medicinally valuable steroids, particularly A-ring aromatic steroids. This process features an early optical resolution and a unique asymmetric induction which insures the correct stereochemistry of the final steroidal product.
