A SYNTHESIS OF (+/-)-Δ2-α-LYCOREN-7-ONE, THE KEY INTERMEDIATE FOR THE TOTAL SYNTHESIS OF (+/-)-LYCORINE

(+/-)-α-Lycoran-3,5-dione (14a) was prepared from octahydrophenanthridin-3-one (8b) obtained by two methods starting from 5-aryl-4-nitrocyclohaxane (2) and 1-hydroxy-2-aryl-5-oxo-cyclohexanecarboxylic acid (10), both of which were prepared by the Diels-Al
