Astonishingly, the title compounds 3 were previously unknown. The first three compounds of this type have now been obtained from the methacrylic acid derivatives 1 via the peroxylactones 2 ; this once more demonstrates the suitability of phosphanes for the deoxygenation of cyclic compounds. The high degree of functionality of 3 is of interest.
