Gold/acid-co-catalyzed direct microwave-assisted synthesis of fused azaheterocycles from propargylic hydroperoxides
Alcaide, Benito,Almendros, Pedro,Quiros, M. Teresa
, p. 3384 - 3393 (2014/04/03)
The gold-acid-co-catalyzed synthesis of nine series of fused azaheterocycles with structural diversity starting from the same synthons as readily available propargylic hydroperoxides and aromatic amines has been achieved. The overall tandem process consists in a gold-catalyzed hydroperoxide rearrangement/Michael reaction followed by a final acid-catalyzed cyclization.
