AbstractThe reactions of 2,3-dihydro-2,2,2-triphenylphenanthro[9,10-d]-1,3,2-λ5-oxazaphospholes with aromatic aldehydes lead to the corresponding 2-substituted phenanthro[9,10-d][1,3]oxazoles via an aza-Wittig reaction in good yields. Graphical abstract

This is a silver(I) mediated C-alpha(sp(3))-H activation of primary amines followed by oxidative C-O cross coupling/cyclization for the construction of 2,4,5-triaryl and 2-alkyl-4,5-diaryl oxazole derivatives. The protocol has been successfully utilized to synthesize the oxazole derivatives in good to excellent yields. In this oxidative coupling, the silver species after the reaction was successfully re-synthesized and reused with almost a similar activity. (C) 2015 Elsevier Ltd. All rights reserved.
