| Description | We report herein a synthesis of two regioisomeric aldehydes with tetrahydrobenzo[b]thiophene skeleton and partially protected allylamino group in ortho position on the thiophene ring. We used them for reaction with five substituted secondary amines under solvent free conditions and conventional heating to in situ formation of azomethine ylides intramolecularly reacting to fused heterocycles. Cyclohexanone was the starting material for both pathways leading to substituted regioisomeric compounds. While a synthesis of first compound was based on literature pattern, a new synthetic protocol for preparation of second compound had to be developed. |
