Unified azoline and azole syntheses by optimized aza-wittig chemistry

Intramolecular aza-Wittig ring closures were applied to synthesize thiazolines, oxazolines, and imidazolines from β-azido thioester, ester, and amide precursors. The cyclization precursors were obtained from amino acid derivatives. Optimized conditions fo

Aza-Wittig access to chiral imidazol(in)es

2-Imidazolines and imidazoles have been accessed by an aza-Wittig sequence featuring novel N-acylation methodology for sulfonamides and optimized conditions for ring closure.
