摘要:一系列双键螯合钯(II)配合物[Pd(Nn)2 ] [X] 2(Nn = 2,2'-联吡啶(Bipy),1,10-菲咯啉(Phen)及其取代的衍生物;X = Pf 6-,Bf 4-,光学传递函数-,在职培训计划-)已被合成并在固态和溶液中完全特征两者.合成过程涉及pd(Mecoo)2之间的简单一锅反应和[(Nn)H] [X].这些化合物是用于co /苯乙烯共聚的非常活跃的预催化剂,可产生完美交替的聚酮.该系列某些配合物的晶体结构提供了证据,表明从理想的方形平面几何结构向扭曲构象发生了扭曲.在dmso溶液中,两个氮供体配体之一参与解离平衡,获得具有两个顺式的单螯合物配位点可用于共聚催化过程.催化活性物质在2,2,2-三氟乙醇中非常稳定,在至少48小时的反应中,其活性均未改变,且未明显分解为钯金属.将1,4-苯醌(Bq)添加到催化体系中对产率尤其是对聚酮的分子量有很大的影响.合成和表

标 题 :Method for the synthesis of pyrrole and imidazole carboxamides on a solid support
发明人：DERVAN PETER B; BAIRD ELDON
权利人:CALIFORNIA INST OF TECHN
摘要:The present invention describes a novel method for the solid phase synthesis of polyamides containing imidazole and pyrrole carboxamides. The polyamides are prepared on a solid support from aromatic carboxylic acids and aromatic amines with high stepwise coupling yields (>99%), providing milligram quantities of highly pure polyamides. The present invention also describes the synthesis of analogs of the natural products Netropsin and Distamycin A, two antiviral antibiotics. The present invention also describes a novel method for the solid phase synthesis of imidazole and pyrrole carboxamide polyamide-oligonucleotide conjugates. This methodology will greatly increase both the complexity and quantity of minor-groove binding polyamides and minor-groove binding polyamide-oligonucleotide conjugates which can be synthesized and tested.

标题:Palladium catalyzed alkylative cyclization useful in synthesis of vitamin D and analogues
发明人：TROST BARRY M; DUMAS JACQUES
权利人:UNIV LELAND STANFORD JUNIOR
摘要:An alkylative cycloaddition method is provided that is particularly useful for the synthesis of many of the Vitamin D analogues with differing side chains. Thus, a preferred synthesis is of Vitamin D analogues having a side chain R 1 where a substantially geometrically pure first precursor having the structure ##STR1## and a second precursor are provided, the second precursor being a 1,7 enyne. These precursors are reacted in the presence of a palladium catalyst to form compounds having the structure ##STR2## where R 2 hydrogen, hydroxyl, lower alkoxy, fluorine, or a protecting group, and R 3 is hydrogen, hydroxyl, lower alkoxy, fluorine, or a protecting group.

摘要:The present invention relates to a process for the regioselective synthesis of compounds of the formula I, n nwherein R0; R1; R2; R3; R4; R5; A1; A2; A3; A4, Q and J have the meanings indicated in the claims. The present invention provides a direct transition metal catalyzed process to a wide variety of multifunctional 2H-indazoles or 2H-azaindazoles of the formula (I) from 2-halo-phenylacetylenes or (2-sulfonato)phenylacetylenes and monosubstituted hydrazines.
