Reactions of N- and C-Alkenylanilines: V. Synthesis of Iodo-Substituted Heterocycles from o-Cycloalkenylanilines and Their Transformations
摘要:
Iodination of N-isopropyl- and N-benzyl-2-(2-cyclohexenyl)anilines gave the corresponding 1-iodohexahydrocarbazoles which underwent quantitative isomerization into 3-iodo-2,4-propano-1,2,3,4-tetrahydroquinolines. Nucleophilic substitution in 1-iodohexahydrocarbazoles and 3-iodo-2,4-propano-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indole was studied. N-Allylation of the latter via reaction with allyl bromide is accompanied by replacement of the iodine atom by bromine.
