Simple and selective single step synthesis of substituted octahydrophenanthridines and annelated pyridines was achieved using simple cyclic ketones, aliphatic aldehydes and ammonia over zeolites as catalyst under high pressure (autogeneous pressure) conditions with high yields and high conversions f
Quaternization of alkynyl substituted pyrazines with triethyloxonium tetrafluoroborate in dichloromethane occurs exclusively at N-4 yielding 3-alkynyl-lethylpyrazinium salts, as shown by the 13C NMR data. Protonation of the same pyrazines with trifluoroacetic acid also occurs at N-4. The quaternary
