Abstract
The reaction of 2,6-diarylidenecyclohexanones with hydrazine hydrate in gla cial acetic acid resulted in the formation of diastereomers of (E)-2-acetyl -3-aryl-7-arylidene-3,3a,4,5,6,7-hexahydroindazoles. The relative configura tions of these diastereomers were unambiguously assigned using H-1 and C-13 NMR spectroscopic methods. (C) 1999 John Wiley & Sons, Ltd.
