directing group for the directed C–H-allylation reactions. Depending on the allylating agent used, selectively either mono- or diallylated products were readily synthesized. Moreover, the trichloro acetimidamide directing group was found to be highly efficient even at lower temperature for the C–H-allylation reaction. Due to mildness of the reaction conditions, double bond isomerization or cyclization
容易合成的三氯乙酰胺是直接C-H-烯丙基化反应的良好指导基团。取决于所用的烯丙基化试剂,容易地选择性地合成单-或二烯丙基化的产物。此外,即使在较低的温度下,CH-H-烯丙基化反应也能有效地控制三氯乙酰胺基。由于反应条件温和,未观察到双键异构化或环化为吲哚副产物。
