The palladium-catalysed domino cyclisation of the aryl bromides 4, containing an alkyne and a bromonaphthyl moiety, leads to tetracycles of type 5 in good yields. The substrates 4 are easily accessible by addition of the corresponding lithiated alkynes 7 to the aldehyde 6. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
包含炔烃和溴萘基部分的芳基溴化物 4 的钯催化多米诺环化以良好的产率产生 5 型四环。通过将相应的锂化炔烃 7 添加到醛 6 中,可以很容易地获得底物 4。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
