A short synthetic strategy for 3,6-disubstituted-N-2-thienyl/aryl-indoles, involving reaction of substituted 2,4-difluoro/dichloro-styrene epoxide with substituted 2-formylaminothiophenes or substituted N-formylanilines in the presence of a base followed by treatment with an acid, has been developed. The method was applied for the synthesis of a number of indoles with a variety of substituents at 1
