  An Investigation of Imidazole and Oxazole Syntheses Using Aryl-Substituted TosMIC Reagents¹

  摘要：

  This article describes efficient and mild protocols for preparing polysubstituted imidazoles in a single pot fi om aryl-substituted tosylmethyl isocyanide (TosMIC) reagents and imines generated in situ. Traditional imine-forming reactions employing virtually any aldehyde and amine followed by addition of the TosMIC reagent delivers 1,4,5-trisubstituted imidazoles with predictable regiochemistry. Employing chiral amines and aldehydes, particularly those derived from or-amino acids, affords imidazoles with asymmetric centers appended to N-1 or C-5 with excellent retention of chiral purity. 1,4-Disubstituted imidazoles are also readily prepared by a simple variant of the above procedure. Selecting glyoxylic acid as the aldehyde component of this procedure leads to intermediates such as 48, which readily undergo decarboxylation and elimination oft;he tosyl moiety to deliver 1,4-disubstituted imidazoles in high yields. Alternatively, using NH4OH as the amine component in conjunction with a variety of aldehydes delivers 4,5-disubstituted imidazoles in moderate to good yields in a single pot while avoiding the need for protecting groups. Finally, the facile preparation of mono- and disubstituted oxazoles from these TosMIC reagents and aldehydes is described.
