A method of synthesising a compound of formula I: comprising the step of reacting a moiety of formula II: with a moiety of formula III: in compressed carbon dioxide in the presence of a transition metal catalyst and a base, wherein L is a labile leaving group; RN1 is optionally substituted C5-20 aryl; RN2 is selected from optionally substituted C5-20 aryl, optionally substituted C3-20 heterocyclyl, optionally substituted C3-7 alkyl, and optionally substituted sulfonyl; RN3 is selected from H and optionally substituted C1-7 alkyl, C3-20 heterocyclyl and C5-20 aryl; or RN2 and RN3 together with the nitrogen atom to which they are attached form optionally substituted nitrogen-containing C3-20 heterocylyl or C5-20 heteroaryl; and R1 R2 and R3 are independently selected from optionally substituted C1-7 alkyl, C5-20 aryl, C3-20 heterocyclyl, hydroxy, halo, amino and C1-7 alkoxy, or two of R1, R2 and R3, together with the silicon atom to which they are attached, may form a silicon containing C5-7 heterocyclyl group.
一种合成式I化合物的方法:包括在压缩二氧化碳存在下,通过将式II的基团与式III的基团在存在过渡金属催化剂和碱的条件下反应,其中L是一种易离去基团;RN1是可选择的取代的C5-20芳基;RN2选自可选择的取代的C5-20芳基、可选择的取代的C3-20杂环烷基、可选择的取代的C3-7烷基和可选择的取代的磺酰基;RN3选自H和可选择的取代的C1-7烷基、C3-20杂环烷基和C5-20芳基;或RN2和RN3与它们连接的氮原子一起形成可选择的取代的含氮C3-20杂环烷基或C5-20杂环芳基;R1、R2和R3独立地选自可选择的取代的C1-7烷基、C5-20芳基、C3-20杂环烷基、羟基、卤素、氨基和C1-7烷氧基,或R1、R2和R3中的两个,与它们连接的硅原子一起,可以形成含硅的C5-7杂环烷基基团。
