| Popis | We report here two synthetic pathways leading to substituted 5,6-dihydro-4H-pyrrolo[1,2-b]pyrazoles. The first procedure starts from g-butyrolactone, which is transformed to 6-chlorohex-1-en-3-one alternatively in 3 or 5 steps. In following 4 steps we are able to prepare final variosly substituted bicyclic compounds. The second route comprises thermally initiated intramolecular cyclizations of substituted homoallenyl azines to desired heterocycles. |
