This invention relates to novel isonitriles, including arylthio isonitriles, and methods for their preparation. The isonitriles include a conjugated ring system. The structure is designed with the flexibility to have multiple substitution patterns. The isonitriles may be used in applications including, but not limited to, pharmaceutical compositions.

Three-component reaction of methyl α,α-disubstituted α-isocyanoacetates, primary amines, and aryl(vinyl) halides in the presence of Pd(OAc)2 (0.05 equiv) and Cu2O (1.0 equiv) provided 2,3,5,5-tetrasubstituted imidazolones via the formation of three chemical bonds. A copper-mediated migratory insertion of the isocyano group into the N–H bond of the amine followed by lactamization and Pd-catalyzed cross-coupling

for the reaction outcome. The same transformation between methyl 2-isocyanobenzoate and amines afforded quinazolin-4-ones in excellent yields. The utility of this chemistry was illustrated by the development of concise syntheses of (±)-evodiamine and rutaecarpine.

We report the use of isonitriles as alkyl radical precursors in visible-light mediated hydro- and deuterodeamination reactions. Most examples only require visible-light irradiation of the isonitrile in the presence of a silyl radical precursor, although a significant acceleration was observed in the presence of an organic photocatalyst. The method is scalable, shows broad functional group compatibility
我们报道了在可见光介导的加氢和氘代脱氨基反应中使用异腈作为烷基自由基前体。大多数例子仅需要在甲硅烷基自由基前体存在下对异腈进行可见光照射,尽管在有机光催化剂存在下观察到显着的加速。该方法具有可扩展性,显示出广泛的官能团兼容性,并且适用于 C α伯、C α仲和 C α叔烷基异腈。
