Cyclization of 2-(1?-alkyl-2?-alkenyl)anilines in polyphosphoric acid
摘要:
The cyclization of 2-alkenylarylamines in polyphosphoric acid (PPA) with 1,2 and 1,3 shifts of the alpha-alkyl substituent of the alkenyl fragment leads to the formation of indoline and indane compounds. Cis- and trans-stereoisomers of 2-methyl-4-ethyl-1-aminoindane formed without displacement of the alpha-substituents as well as 2-methyl-2-propylindoline are obtained from 2-(1'-methyl-2'-pentenyl)aniline.
