Synthetic studies towards complex diterpenoids. Part 20.1 Total synthesis of the linear abietane o-quinone umbrosone
Abstract
A simple total synthesis of the rearranged linear abietane diterpenoid o-quinone, umbrosone 1, has been accomplished through trans-1,2,3,4,9,9a-hexahydro-1,1-dimethyl-6-methoxyanthracen-10(4aH)-one 12t.
