Direct synthesis of conjugated nitroalkeneviaHenry condensation reaction in one-pot often leads to poor conversion and yield due to the reversible nature of β-nitroalcohol intermediate which undergoes reversible reaction in the basic medium. Here we report a synthesis of β-nitroalkene employing L-proline, a bifunctional catalyst, which directs the reaction of aldehyde with nitroalkane to take a different
