CpRu(PPh3)(PR3)Cl complexes, where PR 3 = PMe3, PPh3, or PTA (PTA = 1,3,5-triaza-7-phosphaadamantane), were used to catalyze the atom transfer radical addition of chlorinated esters (CClsu

A series of phenoxybutanoic acid derivatives were synthesized and tested for their antagonistic activity on the contraction of the rat thoracic aortic ring induced by endothelin-1. Preliminary screening results showed that 6e and 6g with benzoheterocycles demonstrated significant antagonistic activities when compared to the reference compound BQ123. The results from additional assays for the binding affinity and selectivity for endothelin receptors showed that 6e was a selective ETA antagonist with a nanomolar IC50. Moreover, 6e was effective in relieving hypoxia-induced pulmonary arterial hypertension and right ventricular weight ratio. Therefore, 6e may have potential for further development as a therapeutic agent for the treatment of cardiovascular diseases.

The Kharasch reaction, or atom-transfer addition of polyhalogenated alkanes to alkenes is known to be catalyzed by a number of Ru(II) complexes. The easily prepared [RuCl2(PPh3)3] was used to investigate the reaction scope. A number of halogenated alkanes were added to a range of alkenes with good to excellent regioselectivities.

In the presence of suitable catalysts and additives, the zinc homoenolate of alkyl propionate and its congeners undergo a variety of carbon-carbon bond-forming reactions, e.g., addition onto carbonyl compounds, allylation, arylation, vinylation, and acylation, to produce diverse kinds of alkanoates and cyclopropane derivatives.The moderately reactive zinc homoenolate exhibited a very high degree of chemoselectivity in these reactions.Me3SiCl has been found to greatly accelerate 1,2- or 1,4-addition and the allylation reaction of the zinc reagent.
