The combination of Ph3PAuCl and AgOTf was proven to be an efficient catalyst for the cascade C–C and C–N bond formation reactions from enamines and bromoquinones or nitroolefins. This protocol affords a straightforward method for the synthesis of polysubstituted indolequinones and pyrroles in good yields.
事实证明,Ph 3 PAuCl和AgOTf的结合是一种有效的催化剂,可用于烯胺,
