  Stereoselective Synthesis of Naturally-Occurring 7-(Hetero) Aryl (2E, 4E, 6E)-2, 4, 6-Heptatrienamides and Their Structural Analogues

  摘要：

  A new and efficient highly stereoselective method to prepare naturally-occurring 7-(hetero)aryl (2E,4E,6E)-2,4,6-heptatrienamides and their structural analogues has been developed. The physical and spectral properties of one of these compounds, i.e. (2E,4E,6E)-7-(2-thienyl)-2,4,6-heptatrienoic acid piperidide (4 b), have been found to be quite different from those previously reported for 7-(2-thienyl)-2,4,6-heptatrienoic acid piperidide isolated from Othantus maritimus to which the (2E,4E,6E)-configuration had been previously assigned.

• (Z)-Selective cross-dimerization of arylacetylenes with silylacetylenes catalyzed by vinylideneruthenium complexes
  作者：Hiroyuki Katayama、Hiroshi Yari、Masaki Tanaka、Fumiyuki Ozawa

  日期：——

  The vinylideneruthenium(II) complexes bearing bulky and basic tertiary phosphine ligands, RuCl2(CCHPh)L2 (L = PPri3, PCy3), serve as good catalyst precursors for (Z)-selective cross-dimerization between arylacetylenes and silylacetylenes in the presence of N-methylpyrrolidine.

• A straightforward synthesis of symmetrical polyendiynes by dimerization reactions of silyl derivatives
  作者：Francesco Babudri、Vito Fiandanese、Giuseppe Marchese、Angela Punzi

  DOI：10.1016/s0022-328x(98)00724-4

  日期：1998.9

  A straightforward synthesis of polyendiynes is described. The method is based upon a simple dimerization reaction of silylated enynes in the presence of copper salts. A variety of polyunsaturated compounds have been obtained in high yields and with high retention of configuration. (C) 1998 Elsevier Science S.A. All rights reserved.
