Abstract

Spirobarbituric acid derivatives are assembled via a [2+2+2] cycloaddition and the Diels-Alder (DA) reaction as key steps. A transient diene 13 containing spiribarbituric acid suitable for DA reaction has been generated in situ from the sultine derivative 12, which in turn was obtained by the usage of rongalite.
