A method for isomerizing a maleate, or a maleate containing a 2-propenyloxy group in the molecule at a high selectivity is provided which employs an isomerizing catalyst containing a Group VIII element. This method produces a fumarate, or a fumarate containing a 1-propenyloxy group in a high yield, which is useful in the fields of resin source materials and plasticizer. This method gives high-purity fumarates containing no catalyst residue by use of a heterogeneous catalyst which is readily separable and non-corrosive.

A total synthesis of the Aspidosperma alkaloid quebrachamine in racemic form is first described. A key catalytic ring-closing metathesis of an achiral triene is used to establish the all-carbon quaternary stereogeniccenter and the tetracyclic structure of the natural product; the cataly tic transformation proceeds with reasonable efficiency through the use of existing achiral Ru or Mo catalysts. Ru- or Mo-based chiral olefin metathesis catalysts have proven to be inefficient and entirely nonselective in cases where the desired product is observed. In the present study, the synthesis route thus serves as a platform for the discovery of new olefin metathesis catalysts that allow for efficient completion of an enantioselective synthesis of quebrachamine. Accordingly, on the basis of mechanistic principles, stereogenic-at-Mo complexes bearing only monodentate ligands have been designed. The new catalysts provide significantly higher levels of activity than observed with the previously reported Ru-or Mo-based complexes. Enantiomerically enriched chiral alkylidenes are generated through diastereoselective reactions involving achiral Mo-bas ed bispyrrolides and enantiomerically pure silyl-protected binaphthols. Such chiral catalysts initiate the key enantioselective ring-closing metathesis step in the total synthesis of quebrachamine efficiently (1 mol percent loading, 22 C, 1h, >98percent conversion, 84percent yield) and with high selectivity (98:2 er, 96percent ee).

A novel series of polymethylene-linked heterobinuclear complexes of polypyridine ruthenium(II)/osmium(II) complex Ru(II)(bpy)2Mebpy-(CH2)n-MebpyOs(II)(bpy)2(bpy=2,2′-bipyridine and N=2, 3, 5, and 7), 1, was prepared.The photophysical behavior was examined in various solvents.The emission spectra of 1 (excitation wavelength: 455 nm) showed a nearly complete quenching of Ru(II) -> ?*(bpy) metal-to-ligand charge transfer (MLCT) emission and the enhancement of Os(II) -> ?*(bpy) MLCT emission.The luminescence lifetime measurements by a time-correlated single photon-counting method provided evidence that intramolecular energy transfer is a significant pathway for the observed emission quenching.The rate constants of the intramolecular energy transfer in ethanol are 5.3 * 108, 3.3 * 108, 1.3 * 108, and 1.0 * 108 s-1 for 1 (n=2, 3, 5, and 7), respectively.They were found to be proportional to the inverse sixth power on the center-to-center distance of the two complexes.The mechanisms is discussed in terms of the Foerster (a dipole-dipole interaction) mechanism.
