Dimethyldioxirane appeared as an efficient oxidant to convert easily and with good yields hopane 1 into hopan-21beta-ol 5 and hopan-17beta-ol 6, both useful precursors for the synthesis of geohopanoids, the other isomers moretane 2,17alpha-hopane 3 and 17alpha-moretane 4 being much more resistant to oxidation.

On heating in liquid sulphur, the unsaturated hopanoid hop-17(21)-ene 1 was converted to a major extent into the series of organo-sulphur products 5–9, all interest as potential sedimentary biomarkers.
