It has been found that the addition of cupric oxide to the cross-coupling reaction (Stille reaction) of 2-tributylstannylpyridine with various halobenzenes and heterocyclic halides leads to a much faster reaction and higher yields. This is also the case for the formation of thieno[3,2-h]-1,6-naphthyridine from 2-(2-trimethylstannyl-3-pyridyl)-1,3-dioxolane and t-butyl-N-(2-bromo-3-thienyl)carbamate
已经发现,在2-三丁基苯乙烯基吡啶与各种卤代苯和杂环卤化物的交叉偶联反应(Stille反应)中加入氧化铜导致反应更快,产率更高。由2-(2-三甲基锡烷基-3-吡啶基)-1,3-二氧戊环和叔丁基-N-(2 )形成噻吩并[3,2 - h ] -1,6-萘啶的情况也是如此。-溴-3-噻吩基)氨基甲酸酯。
