Reaction Conditions:
with lithium aluminium hydride in tetrahydrofuran at 0 - 80; for 15 h;
Steps:
b) Reduction of nitro-alkenes.
General procedure: A solution of the nitro-alkene compound (1 equiv.) in anhydrous THF (10 mL/200 mg) wasadded dropwise to a suspension of LiAlH4 (4 equiv.) in anhydrous THF at 0 °C. The reactionmixture was then stirred at 80 °C overnight. After cooling to 0 °C, water (35 mL) and 4Naqueous NaOH (35 mL) were added slowly. The suspension was filtered on celite, the filtratewas partially evaporated and extracted with DCM (3 x 50 mL). The organic phases werecombined and extracted with 2N aqueous HCl (3 x 50 mL). The aqueous phases were combined,adjusted to pH = 9 with NH4OH, and extracted with DCM (3 x 50 mL). The organic phaseswere combined and washed with water (2 x 50 mL), brine (50 mL), dried over MgSO4, filteredand evaporated to yield the corresponding amine compounds. For some compounds, theobtained solid was solubilized in a minimal volume of diethyl ether and treated with a 2N HClethereal solution. Hexane was then added. After slow evaporation, a solid was formed, filteredand washed with hexane to give the hydrochloride salt. Compounds 10 and 11 were used in thenext step without further purification.-
