with 2-iodophenol. In particular, N-tosyl-protected dienylanilines can be transformed under mild conditions into quinolines and quinolinones, in the presence of a PdII catalyst. Moreover, the cross-coupling reaction between butadienylboronic esters and iodophenol directly affords chromenes that can be successively transformed into chromenones. (© Wiley-VCH Verlag GmbH & Co.

烷氧基官能化丁二烯基硼酸酯已从 α,β-不饱和缩醛开始合成,并与 N-保护和 N-未保护的 2-溴和 2-碘苯胺以及 2-碘苯酚交叉偶联。特别是,在 PdII 催化剂的存在下,N-甲苯磺酰基保护的二烯基苯胺可以在温和条件下转化为喹啉和喹啉酮。此外,丁二烯基硼酸酯和碘苯酚之间的交叉偶联反应直接提供可以连续转化为色酮的色烯。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
