Abstract

Ortho-allylanilines were cyclized to indoles using a palladium(II)-catalyzed intramolecular amination of the olefinic side chain. A general approach to diaminobenzoquinones was developed, and preliminary studies of a palladium(II)-catalyzed approach to the mitomycins were initiated. o-Bromo- N-allylanilines were cyclized to indoles or quinolines using palladium(O) catalysis. Non-aromatic olefinic amines were converted to their sulfonamides and cyclized to sulfonated cyclic enamines using palladium(II) catalysts. A new synthesis of β-lactams from imines and chromium carbene complexes was developed.
