THE CHEMISTRY OF THE PYRIDOCARBAZOLES PART 15. THE SYNTHESIS OF UNSYMMETRICALLY 1,4-DISUBSTITUTED CARBAZOLES AND THEIR USE IN THE SYNTHESIS OF 6H-PYRIDOCARBAZOLES
A new construction of unsymmetrically 1,4-disubstituted carbazoles has been devised and used in the synthesis of the alkaloid olivacine.The starting materials are gramines and the sodium salts of 2-cyano-4-oxopentanonitriles.These afford 4-cyano-5-(indol-
