Quinolines substituted in the 3-position by an iodo or phenylseleno group are readily prepared in good to excellent yields by the reaction of propargylic anilines with appropriate electrophiles under mild reaction conditions. [reaction: see text]
A visible-light-induced cascade cyanoalkylsulfonylation/cyclization/aromatization of N-propargyl aromaticamines with K2S2O5 and cyclobutanone oxime esters for the construction of cyanoalkylsulfonylated quinolines is developed. This cascade transformation features mild reaction conditions, a broad substrate scope, and excellent functional group compatibility, providing a convenient route toward cy
开发了N-炔丙基芳香胺与 K 2 S 2 O 5和环丁酮肟酯的可见光诱导级联氰烷基磺酰化/环化/芳构化,用于构建氰烷基磺酰化喹啉。这种级联转化具有反应条件温和、底物范围广、官能团兼容性好等特点,通过一步形成一个 C-C 键和两个 C-S 键,提供了一条通往氰基烷基磺酰化喹啉的便捷途径。
