The syntheses of a variety of substituted diaminomaleonitriles, with variable nitrogen substituents, were undertaken. Linstead macrocyclization of the resulting diaminomaleonitriles gave access to a wide range of functionalized porphyrazine-octaamine

The amino-functionalized porphyrazines 1, 2, and 4 and norphthalocyanines 3 and 5, which were prepared via Linstead macrocyclization reactions of dinitrile precusors, were subject to UV-vis titrations in the presence of inorganic ions. These polydent

Thio N-acyliminium ions are readily generated from the reaction of thioamides with bromoacetyl chloride. In the presence of tethered π-nucleophiles, cyclization occurs to give S,N-acetals which can be further converted into various alkaloid skeleton

Ammonium ylides derived from the Cu(II)-catalyzed decomposition of α-diazo carbonyls tethered to tertiary amines underwent a benzylic Stevens [1, 2]-rearrangement to give tetrahydroisoquinolines or benzazepines containing fused five-membered rings,

Linstead macrocyclization of dinitrile 1 gave [octakis(dimethylamino)porphyrazinato]magnesium(II) 2 and the seco-porphyrazine 4 from adventitious oxidation. The structure of the latter has been unequivocally established by an X-ray crystallographic s

A highly effective method for the synthesis of the core indolo[2,3-alpha]quinolizidine skeleton found in yohimbine is described. The reaction of N-monosubstituted thioamides with bromoalkenoyl chlorides furnishes thioisomünchnones as transient 1,3-d
