Ruthenium catalyst TpRuPPh(3)(CH(3)CN)(2)Cl is found to effect the cyclization of epoxyalkynes to furans in the presence of Et(3)N. The reactions worked well for various epoxyalkynes with suitable oxygen and nitrogen functionalities with low loading of catalyst. It failed with disubstituted epoxyalkynes. The mechanism was elucidated by a deuterium labeling experiment that suggested that the mechanism
Direct bromination and iodination of the trispyrazolyl borate ligand in TpRu(nbd)Cl and the effect of Tp4−X ligands on redox potentials and catalysis

ligands often require extreme conditions that are incompatible with some pyrazole derivatives. In contrast, an alternative direct functionalization of the Tp ligand could offer more compatible conditions. To prove this principle, direct bromination or iodination of TpRu(nbd)Cl is reported herein, and Sonogashira cross-coupling of the iodinated ligand with an alkyne could be performed at ambient temperature
The Baeyer-Villiger Oxidation of 8-Oxabicyclo[3.2.1]octan-3-ones. Substituent Effects on the Regioselectivity

8-Oxabicyclo[3.2.1]octan-3-one derivatives serve as excellent models that elucidate factors controlling the reactivities and selectivities in the Baeyer-Villigeroxidation. The regioselectivity of ...
The Diels-Alder cycloaddition reaction of some substituted furans and E-1,2-bis(phenylsulfonyl)ethylene

The Diels-Alder cycloaddition between several 2-, and 3-substituted furans and E-1,2-bis(phenylsulfonyl)ethylene have been carried out in high yields. Stereoselectivity observed in the case of 2-sustituted furans has been explained by means of the MM3-transition state model. The model had to be refined for 2-methoxyfuran due to the asymmetry induced over the transition state geometry by the electron-donating
