An eco‐friendly, straightforward, and three‐component [2+2+2] cycloaddition reaction of 4‐aryliden‐2‐phenyl‐5(4H)‐oxazolones and substituted β‐nitrostyrenes to construct diversified 3‐oxa‐1‐azaspiro[4.5]dec‐1‐en‐4‐ones has been developed with good yields and regio‐ and diastereoselectivity. This reaction proceeds via a one‐pot [2+2+2] cycloaddition utilizing cesium carbonate as a promoter and shows high atom economy under the reaction conditions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Asian Journal of Organic Chemistry Wiley

Abstract

An eco‐friendly, straightforward, and three‐component [2+2+2] cycloaddition reaction of 4‐aryliden‐2‐phenyl‐5(4H)‐oxazolones and substituted β‐nitrostyrenes to construct diversified 3‐oxa‐1‐azaspiro[4.5]dec‐1‐en‐4‐ones has been developed with good yields and regio‐ and diastereoselectivity. This reaction proceeds via a one‐pot [2+2+2] cycloaddition utilizing cesium carbonate as a promoter and shows high atom economy under the reaction conditions.
