Novel azaenamines incorporating a tetrahydrothiophene moiety were prepared. Michael addition of an azaenamine with ,-unsaturated nitriles took place to give [1]benzothieno[3,2:5,6]pyrimido[1,2-b]pyridazine (thia-triaza-benzo[a] fluorene) derivatives. The condensation with malononitrile resulted in the formation of a [1]benzothieno[3,2:5,6]pyrimido[1,2-b]pyridazine-4-carbonitrile. The azaenamine also reacted with aldehydes and piperidine to give Mannich products. Georg Thieme Verlag Stuttgart · New York.
