Abstract: A study of the solvolysis reactions of the chrysanthemyl system is reported. In water the chrysanthemyl cation (2) gives the naturally occurring monoterpene alcohols chrysanthemol (1-OH), artemisia alcohol (3-OH), yomogi alcohol (1 1-OH), and santolina alcohol (5-OH). Rupture of the C (1')-C (3') cyclopropane bond of 2 gives an isomeric allylic cation which reacts with solvent to yield artemisia alcohol (3-OH) and yomogi alcohol (1 1- ...
