supporting information, p. 2446 - 2450 (2013/03/14)
gem-Dihydroperoxides were successfully used for the enantioselective epoxidation of tertiary and primary allylic alcohols. Epoxides derived from tertiary alcohols were obtained in yields up to 71% with ee's up to 52%.
Enantioselective epoxidation of 2-substituted 1,4-naphthoquinones using gem-dihydroperoxides

supporting information; experimental part, p. 4629 - 4632 (2009/10/26)
New gem-dihydroperoxides were successfully used for DBU-promoted enantioselective epoxidation of 2-substituted 1,4-naphthoquinones. The corresponding 1,4-naphthoquinone epoxides were obtained in yields up to 97% and ee's up to 82%.
Reaktionen des (+)-Thujons und (-)-Isothujons mit Formaldehyd
Brieskorn, Carl Heinz,Schwack, Wolfgang
, p. 1993 - 2000 (2007/10/02)
(+)-Thujone and (-)-isothujone react with formaldehyde to give 4β-(hydroxymethyl)thujone (1) and the 2-methylene derivatives 6 and 7.Oxidation of 1 gives thujone-4β-carboxylic acid (2) which decarboxylates to (+)-thujone. 1 is reduced to the isomeric 4β-(hydroxymethyl)- (3a, 3b) and 4-methylthujanols (4a, 4b). 3-Methylthujanol is oxidized to 4-methylthujone (5).
EPIMERISIERUNG VON (-)-THUJON ZU (+)-THUJON
Brieskorn, Carl Heinz,Schwack, Wolfgang
, p. 255 - 256 (2007/10/02)
(-)-Thujone is quantitatively epimerized to (+)-thujone over 4-hydroximethylthujone and thujone-4-carboxylic acid.
