The reaction of 2,6-diarylidenecyclohexanones with hydrazine hydrate in glacial 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 conÐgurations of these diastereomers were unambiguously assigned using 1H and 13C NM

The anellation of a 6-membered ring to the 2,3-position of corannulene ( dibenzo[ghi,mno]fluoranthene; 1) leads to curved aromatic compounds with a significantly higher bowl-inversion barrier than corannulene (see Fig. 1). If the bridge is ÀCH 2 ÀNRÀCH 2 À, a variety of linkers can be introduced at
