Straightforward strategy for the stereoselective synthesis of spiro-fused (C-5)isoxazolino- or (C-3)pyrazolino-(C-3)quinolin-2-ones from Baylis-Hillman adducts by 1,3-dipolar cycloaddition and reductive cyclization

A straightforward and general approach for the stereoselective synthesis of spiro-fused (C-5)isoxazolino- or (C-3)pyrazolino-(C-3)quinolin-2-ones from the adducts offorded from the Baylis-Hillman reaction of 2-nitrobenzaldehyde and ethyl acrylate by sequential 1,3-dipolar cycloaddition and reductive cyclization is presented. It was found that the reductive cyclization of the isoxazoline derivatives proceeded efficiently in the presence of In/HCl, whereas similar reductions of pyrazolines gave better yields when carried out in the presence of an Fe/AcOH mixture. However, similar attempts employing the Baylis-Hillman adduct of 2-nitrobenzaldehyde and methyl vinyl ketone did not yield the desired compounds. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

Morita–Baylis–Hillman adducts, prepared from 2-nitrobenzaldehyde precursors and either methyl acrylate or methyl vinyl ketone, have been used as critical synthons in the preparation of α-[(alkylamino)methyl]cinnamate esters and their but-3-en-2-one analogs, cinnamate ester-azidothymidine (AZT) conjugates, 2-quinolone and quinoline derivatives. Computer docking studies have been conducted to explore the potential of the cinnamate ester–AZT conjugates as potential dual-action HIV-1 integrase–reverse transcriptase (IN–RT) inhibitors. The results further demonstrate the applicability of Morita–Baylis–Hillman methodology in the construction of complex drug-like scaffolds.

Baylis-Hillman reactions of 2-nitrobenzaldehydes with various activated alkenes afford adducts that undergo reductive cyclisation to quinoline derivatives. The chemo- and regioselectivity of cyclisation appears to be influenced by the choice of both the substrate and the reagent system, and competing reactions have been observed.

Reductive cyclization of o-nitro-substituted Baylis-Hillman acetates by carbon monoxide, catalyzed by [Cp*Fe(CO)2]2, gives moderate to good yields of 3-substituted quinolines.
