ORGANOCATALYTIC CARBONYL-OLEFIN AND OLEFIN-OLEFIN METATHESIS

The present invention provides, inter alia, organocatalytic carbonyl-olefin metathesis process. This process involves contacting a carbonyl-containing moiety with an olefin-containing moiety in the presence of a catalyst and under conditions sufficient to form a metathesis product with the proviso that the process takes place in the absence of photochemical promotion, stoichiometric amounts of transition metals, and Brnsted and Lewis acid catalysts. The present invention also provides an organocatalytic olefin-olefin metathesis process. This process involves contacting a first olefin-containing moiety with a second olefin-containing moiety in the presence of a catalyst and under conditions sufficient to form a metathesis product with the proviso that the process takes place in the absence of stoichiometric amounts of transition metals. Products made by the processes disclosed herein are also provided.

Reductive Cleavage of the Nitrogen-Nitrogen Bond in Hydrazine Derivatives

The reductions of the 1,2-disubstituted hydrazines (4) - (7) having the activating groups toluene-p-sulphonyl, acetyl, ethoxycarbonyl, and trifluoroacetyl respectively have been studied with zinc in acetic acid, aluminium amalgam, sodium in liquid ammonia, sodium in ethanol, and Raney nickel.Satisfactory conditions have been defined for the reductive cleavage of each of these substituted hydrazines (4) -(7).The Diels-Alder adduct (12) of cyclopentadiene and diethyl azodicarboxylate has been oxidised, by m-chloroperoxybenzoic acid to give the epoxide (20), by osmium tetraoxide to give the diol (21), and via hydroboration to give the alcohol (22).Using sodium in liquid ammonia these hydrazine derivatives (20)-(22) and others have been reduced by cleavage of the nitrogen-nitrogen bond to give derivatives of oxygenated cyclic diamines.
