Synthesis of (±)-1-desoxy-2-lycorinone and of a possible trans-dihydro-lycoricidine precursor

En-route from the 5-aryl-3-hydroxy-4-nitro-cyclohexanones $\text{1}$ and $\text{2}$, readily available from poly-enolates and 3.4-methylenedioxy-w-nitro-styrene, to dihydro-lycoricidine $\text{3}$ and to lycorine $\text{4}$, respectively, the title compounds $\text{9}$ and $\text{14}$ are prepared in few steps.
