An unusual synthesis of functionalized F-alkyl indoles using ethyl perfluoroalkynoates and C,N diphenyl nitrone is described. Two isomers, 2- F-alkyl (90%) and 3- F-alkyl (10%) are obtained with short perfluoro alkyl chains (CF3, nC3F7). Regiospecifity is obtained with longer chains (C5F11, C6F13, C7F15).
描述了使用全氟链烷酸乙酯和C,N二苯基硝酮不寻常地合成官能化的F-烷基吲哚的方法。获得具有短的全氟烷基链(CF 3,nC 3 F 7)的两种异构体,2-F-烷基(90%)和3-F-烷基(10%)。区域特异性是通过更长的链(C 5 F 11,C 6 F 13,C 7 F 15)获得的。

N-ethylaminopropanoate (secondary amine) to ethyl 3-F-alkylpropynoate leads in excellent yields to enaminoesters of Z and E configuration respectively. Heterocyclic compounds (pyrrolidone) are obtained from Z enaminoesters in three steps: hydrogenation followed by methylation and cyclisation in alkaline medium.

Diels-Alder reactions of Ethyl F-alkyl propynoates with different substituted furans and pyrroles were realised.Different products were obtained according to the substituents of the heterocyclic dienes and more surprisingly with the length of the F-alkyl chain.

The Diels-Alder reactions of ethyl 3-F-alkylpropynoates with cyclopentadiene, tetracyclone (tetraphenylcyclopentadienone) and anthracene have been achieved.The corresponding addition products were obtained with cyclopentadiene and anthracene. With tetracyclone, ethyl 2-F-alkyl-3,4,5,6-tetraphenylbenzoate was obtained.
