late-stage [11C], [13C] and [14C]carbon isotope labeling of cyclic carbamates is reported. This protocol allows the incorporation of carbon dioxide, the primary source of carbon-14 and carbon-11 radioisotopes, in a direct, cost-effective and sustainable manner. A disconnection/reconnection strategy, involving ring opening/isotopic closure, was also implemented.
据报导了环状氨基甲酸酯后期[ 11 C],[ 13 C]和[ 14 C]碳同位素标记的一般程序。该协议允许以直接,经济有效和可持续的方式掺入二氧化碳(碳14和碳11放射性同位素的主要来源)。还实施了涉及开环/同位素封闭的断开/重新连接策略。
