Abstract: A stereoselective aminoiodination of activated alkynes with PhI(OAc)2 and amines via multiple-site functionalization to afford (Z)diethyl 2-(diphenylamino)-3-iodomaleate derivatives with superior yields has been described. The key feature of this reaction is the incorporation of iodide…

Abstract: Transformations of 2-methyl-1-phenylethynyl-1,2,3,4-tetrahydroisoquinoline resulting from the action of activated alkynes in trifluoroethanol and hexafluoroisopropanol were studied. In reactions with dimethyl acetylenedicarboxylate, 6-phenylethynyl-substituted benzazocines were prepared, while methyl 4-benzyl-5-(2-ethenylphenyl)-1-methyl-1H-pyrrole-3-carboxylate and benzo[d][3]-azacyclodeca[4,6,7]triene with the allene fragment, respectively,…

Abstract: A visible-light-mediated difunctionalization of activated alkynes with boronic acid is unveiled to synthesize 3-alkylated coumarins and unsaturated spiro-lactones. The substituent at the para-position of the aryl ring of aryl alkynoate plays a pivotal role in…
