This review discusses syntheses leading to a new type of N-vinylpyridiniuin salts, to novel anionocyanines, to aminophenazines and alloxazines, as well ar to (aza-jdehydroquinolizinium, acridizinium, and morphanthridizinium salts. In addition, Mannich reactions and aminoallcylatioiis at active methylene groups of cycloimnionium SGdtS, and their reactions with amines are treated. The possibilities offered by /he "Ortoleva-King" reactioii are demonstrated using numerous exanzpks, such as a new route leading to the yohimbine skeleton.
