2-Hydroxy- and 2,15-dihydroxyhexahelicene were synthesised from simple benzene and naphthalene building blocks by intramolecular CoI- or Ni0-catalysed [2+2+2] cycloisomerisation of CH3O-substituted aromatic triynes. This approach avoids vexing photodehydrocyclisation of stilbene-type precursors, providing thus a useful alternative to classical procedures. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451
通过分子内 CoI 或 Ni0 催化的 CH3O 取代的芳族三炔的 [2+2+2] 环异构化,从简单的苯和萘结构单元合成了 2-羟基和 2,15-二羟基六螺旋。这种方法避免了二苯乙烯型前体令人烦恼的光脱氢环化,从而为经典程序提供了一种有用的替代方法。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
