Azidobenzeneamines, obtained by C-H activation of aromatic amine precursors, react with aldehydes, acids, and isocyanides to produce Ugi products, which are transformed to benzimidazoles or quinoxalinones with four potential points of diversity by further reaction with triphenylphosphine. [ABSTRACT FROM AUTHOR]

Passerini or Ugi condensations, coupled with an intramolecular Wittig reaction give access to the title compounds. [ABSTRACT FROM AUTHOR]

This four-component reaction of 2-aminobenzoyl azides, aldehydes, carboxylic acids, and isocyanides gives Ugi-products as intermediates, which are converted to isocyanates in refluxing toluene. [ABSTRACT FROM AUTHOR]

The one-pot title reaction starts from aryl substituted Baylis-Hillman phosphonium salts, arylglyoxylates, alkyl cyanides, and primary alkyl amines and does not tolerate aryl amines. [ABSTRACT FROM AUTHOR]

Ugi reaction products (V) react with PPh3 via sequential Staudinger and intramolecular aza-Wittig reaction to 2-acylquinazolines and/or 1,4-benzodiazepin-3-ones depending on steric and electronic effects of the R2-group. [ABSTRACT FROM AUTHOR]

The reactions of phosphonium salts, arylglyoxals, amines, and isocyanides give dihydrobenzazepinones in good yields via a sequential Ugi condensation and intramolecular Wittig reaction. [ABSTRACT FROM AUTHOR]

Title compounds (V) and (VII) are synthesized in a facile one-pot procedure by a new sequential Ugi 4CC/Staudinger/aza-Wittig reaction. [ABSTRACT FROM AUTHOR]

Baylis-Hillman-derived azides (I) react with PPh3 to generate iminophosphoranes which undergo aza-Wittig reaction with aryl isocyanates. [ABSTRACT FROM AUTHOR]
