The Au(I)-catalysed rearrangement of propargylic esters formed from an ynamide has been studied. The reaction is facile, and when conducted in the presence of a reactive indole nucleophile, leads to a cascade process whereby γ-indolyl α-acyloxyenamides are formed in good yield and excellent E-stereoselectivity.
已研究了从ynamide生成的丙炔酯的Au(I)催化重排反应。该反应简单易行,在反应活泼的吲哚亲核试剂存在下,会导致级联反应,生成γ-吲哚基α-酰氧烯酮,产率良好且具有优异的E-立体选择性。
