The saturated endoperoxide 1 reacts at 60–80°C via the allene oxide 2 and its ring-opened product 3 by a [3,4]-sigmatropic shift to form the 5-oxo-6-heptenal derivatives 4. The reaction might also be applicable to heteroatom analogues of 1. References 1 I. Erden, M. Amputch, Tetrahedron Lett. 1987, 28, 3779. 2 I. Erden, J. Drummond, R. Alstad, F.-P.

Nishizawa, R. Noyori, Bull. Chem. Soc. Jpn. 1981, 54, 2233. 8 M. J. S. Dewar, Angew. Chem. 1971, 83, 859; Angeww. Chem. Int. Ed. Engl. 1971, 10, 761. 9 Most of the requisite fulvenes were prepared from the corresponding carbonyl compounds and cyclopentadiene by Little's method: (a) K. Stone, R. D. Little, J. Org. Chem. 1984, 49, 1849. Fulvenes 13 and 14 were obtained with NaOMe as base: (b) I. Erden, F.-P. Xu, A. Sadoun, G. Sheff, M. Ossun, J. Org. Chem. 1995, 60, 813. Endoperoxides 9–14 were prepared by low-temperature photooxoygenation of the respective fulvenes at −78°C followed by diazene reduction of the unsaturated endoperoxides at about −40°C [1.10]. 10 W.
