Mixed aldol condensation of 1-oxo-1,2,3,4-tetrahydrocarbazoles 1a-e with thiophene-2-carbaldehyde yielded 2-thienyl-1-oxo-1,2,3,4-tetrahydrocarbazoles 2a-e. Treatment of 2a-e with hydrazine hydrate and hydroxylamine hydrochloride afforded 4,5-dihydrothienyl-2H-pyrazolino[3,4-a]carbazoles 3a-e and 4,5-dihydro-3-thienylisoxazolo[3,4-a]carbazoles 4a-e respectively. All the newly synthesized compounds were characterized by spectral and analytical data.
