distinct reactions, the first, cyclization of 2-(alkynyl)aryl isocyanates with benzylic alcohols, and the second, [1,3] rearrangement of a benzyl group from oxygen to carbon, furnishing 3,3-disubstituted oxindoles in one pot.
钯配合物依次促进了两个机理上不同的反应,第一个是将2-(炔基)芳基异氰酸酯与苄醇环化,第二个是[1,3]苄基从氧到碳的重排,得到3,3-一锅中加入双取代的羟吲哚。
