Abstract
A reaction between 3-isothiocyanato oxindoles and β,γ-unsaturated α-keto esters catalyzed by a chiral thiourea organocatalyst via a domino Michael-cyclization process is described, which delivers a range of biologically important 2′-thioxospiro[indoline-3,4′-oxazolidin]-2-one compounds in high yields with good diastereo- and enantioselectivities (up to 99% yield, >99:1 dr, >99% ee). Moreover, two of 2′-thioxospiro[indoline-3,4′-oxazolidin]-2-one compounds were found to significantly behave in anti-inflammatory activities in a preliminary biological evaluation.
