The functionalization of carbon dioxide (CO2) into high-value building blocks is a relevant topic in carbon isotope labeling, where CO2 is the primary carbon source. A catalytic methoxylation of aryl halides directly from [13C] and [14C]CO2 is reported. Relying on the intermediacy of the methoxyborane BBN-OCH3, as a new secondary nucleophilic labeled source, this strategy allowed labeling of a series
将
二氧化碳 (CO 2 ) 功能化为高价值构建单元是碳同位素标记的相关主题,其中 CO 2是主要碳源。报道了直接从 [ 13 C] 和 [ 14 C]CO 2催化甲氧基化芳基卤化物。依靠甲氧基
硼烷 BBN-OCH 3的中介作用,作为一种新的二级亲核标记源,该策略允许标记一系列底物,包括具有挑战性的含有叔烷基胺取代基的药物。
