    Indoles

    Dinordeoxy-10-methylhomoeseroline and a number of its derivatives, substituted in the benzene ring and at the indole nitrogen atom, were obtained by condensation in neutral, aqueous alcoholic solutions of aryl...

    Indoles

    The ring-chain tautomerism of compounds with the eserine skeleton has been investigated by UV and PMR spectroscopy. It is shown that these compounds exist in neutral solution in the cyclic α-aminoindoline form. I...

    Pyrazoles

    The IR, UV, and NMR spectra of 3- and 5-pyrines, and of their thio, seleno, and imino analogs, are examined, and their pKa values measured. On the basis of the results, it is suggested that protonation in these s...
