Metabolism of Monoterpenes: Demonstration of (+)-Neomenthyl-beta …

WebThe neomenthol, however, is largely converted to neomenthyl-β-d-glucoside (80) which is transported from the leaf to the rhizome where the glycoside is rapidly hydrolyzed. The aglycone is then oxidized back to menthone which undergoes an unusual lactonization reaction to form 3,4-menthone lactone ... WebAs a result, E2 elimination is about 40 times faster for neomenthyl chloride than menthyl chloride because there is less steric strain in the transition state for neomenthyl … install helm windows server
