title: Synthesis of 4,5-seco-eudesman-type sesquiterpenes: 4,5-dioxo-10-epi-4,5-seco-gamma-eudesmane and 4,5-dioxo-10-epi-4,5-seco-gamma-eudesmanol.
abstract: A facile synthetic route to two seco-eudesmanes, 4,5-dioxo-10-epi-4,5-seco-gamma-eudesmane (1) and 4,5-dioxo-10-epi-4,5-seco-gamma-eudesmol (2) from (+)-dihydrocarvone has been described. Avoiding expensive reagents, this highly economic method is especially suited for the synthesis of 4,5-seco-eudesman-type and iphionan-type sesquiterpenes with a double bond at positions 11 and 12.
