Stereoselective electrophilic reactions using azaallyllithium reagents generated from acyclic imidate esters
(1983)
The generation and synthetic utility of azaallyllithium reagents from acyclic imidate esters was described. The acyclic imidate esters 5-15, 18-22, 31-33, 34, 36 and 37 were prepared by various methods. Azaallyllithium ...
Synthesis and evaluation of the biological activity of analogues of leupeptin
(1983)
Leupeptin, N-acetyl or N-propionyl-L-leucyl-L-leucyl-DL-argininal, is a potent inhibitor of trypsin-like enzymes; however, it is not selective within this proteolytic class. In an effort to increase selectivity among ...
The synthesis and structural characterization of dinuclear and triniuclear vanadium complexes
(1983)
The reactions of VCl(,2)(.)2THF and VCl(,3)(.)3THF with ligands capable of functioning as three atom bridges between metal atoms were studied. Several new dimeric and trimeric vanadium complexes in oxidation states II to ...
