摘要：
It was discovered that functionally substituted tetrahydroindazoles can be aromatized by the action of sulfur. Previously unknown 3-R2-4-R1-5-acetyl(ethoxycarbonyl)-6-methylindazoles were obtained. The products from aromatization cannot be obtained if a nitro group is introduced or one heteroatom in the substrate is replaced by oxygen. ©1999 KluwerAcademic/Plenum Publishers.
