Popis: Two different strategies have been developed to perform the gold-catalyzed benzannulation of both electron-rich pyridine containing oxoalkynes with electron-rich alkynes as well as electron-deficient pyridine containing oxoalkynes with electron-deficient­ alkynes. The benzannulation between electron-rich oxoalkynes with electron-rich alkynes proceeds in the presence of highly electron-deficient gold catalysts, whereas using catalytic amount of alcohol benzannulation was performed efficiently between electron-deficient oxoalkynes with electron-deficient alkynes.
