    • Surprisingly, 1j turned out not be a superb dienophile, but an excellent heterodiene. Thus, even with reactive dienes as such cyclopentadiene and 2,3-dimethylbuta-diene the yields of the respective cycloadducts were far from quantitative. Furthermore, in contrast to cyclopropylidenemalonate, which in the presence of sodium azide underwent 1,3-dipolar cycloaddition Ref, 18, 1j under similar reaction conditions afforded the respective Michael adduct
